The Teenage Brain by Adriana Galvan | Santa Clara International School

Introducing Dr Adriana Galvan Hi everyone, How are you? Good, you can sit down I have some pictures to show you about the brain I am going to introduce my self a little bit I am a professor at UCLA, and I have a research laboratory where we do experiments with teenagers because we want to understand how the brain works and how the brain changes during adolescence What is an adolescence? You guys know? No? Are you guys adolescence? Yeah, adolescentes? Teenagers, yeah. Are you guys teenagers? So, what makes a teenager? Yeah, that’s true, being older than thirteen One way that we can find it by age, What else? Am I a teenager? Body, exactly How your face looks, how your body looks My son is seven, is he a teenager? No, how do you know that he is not a teenager? He is too young Often, kids are shorter.. Not always but usually by size, by age. What else? yeah teenagers are cool teenagers have different behaviors, right? behaviors like the way we act changes when we are teenagers you guys remember it’s like not to be a teenager? no? you were five or six exactly and that’s exactly what he said that there was no change that went like that it was not like one minute you were a child and then the next minute you were a teenager it happened slowly over time right one day you just now know that your teenager you’re no longer a child you’re no longer a little child but yet you’re not an adult you’re not like me right you’re not like like this professors in your teachers into my job is to study how that how does that we know and you know that you are a teenager. Okay so I’m going to show you some research that we’ve been doing today on the teenage brain to better understand why change body by the way I’m a parent here at Santa Clara My son is a seven year old and they have given some money for me to country research in Spain and that’s why I’m here because there’s a lot of research going on in Spain on neuroscience the study of the brain okay so maybe you see this before but this is the brain when this when a baby is in the mom’s belly and we use shirt off the brain looks like that like a tiny little tackle and by the time you’re born it’s very complicated so most of the development the max really great happens before you’re born and in terms of the

size and the shape and the weight looks but the way the brain functions the way the brain works changes all things how old would you be your brain stops growing your brain stops maturity yeah 20 something you’ve got 25 26 so right now your brain is changing a lot in fact your brain is changing more now than it ever will in your life and that’s because you’re learning so many things because you’re starting to discover that you’re interested in social relationships maybe your friendships are your child maybe you start being interested in romantic relationships that also happen with the teenagers that are no if you’ve experienced up but all of that happens because of the changes in your brain and then eventually you get to have a brain that looks like this and in your brain you don’t have all these colors you’re the brains gray or pink are very very neutral with these this picture shows you all the different pathways that have to get set up in your brain and the way that setup happens is because of the things that we feed our brain and we feed our brain the relationships we have the learning we do in school the languages that we’re learning many of you know most of the languages are yeah so that’s amazing because in the United States most people in one language they know English and that’s it and so that’s the baby is nobody more linked we just actually helps create these pathways in your brain because language is kind of like a game that you’re braving the storm every minute you learn is very important to feed your brain um but what I’m going to talk to you about today is how how the teenage brain gets up that was going to show you this baby brain don’t work but the teenage brain is something that many people around the world want to understand why do you think that is they don’t understand exactly do you just feel like adults don’t understand sometimes even though we were all teenagers sometimes we feel like we don’t understand teenagers and that’s what we want to know how does the teenage brain works what why did he need is the way that you what are some stereotypes or characteristics that people might have of teenagers I don’t know about in Spain but I know in the u.s. because some stereotypes centimeters what is it here amazing lazy what else you like to go out they like to go out that’s fine yeah what up more independence exactly don’t want to speak independence all of those things we say about teenagers in the u.s. do we also say that teenagers sometimes are impulsive that teenagers take risks the service you might be some danger you might do things that adults find is stupid I’ll show you something I didn’t know as a teenager that was pretty stupid I don’t know if you do it here you guys do something called cheating you guys anything okay this is the very thing that teenagers do we go to people’s houses and put the paper all over their house and then we spray it with water so it’s very far very challenging people to clean it up and this is that are very stupid and the police come and the please take you to jail when you do this and don’t we wonder why do we do these things when we’re teenagers why is that fun things to do and why do you make those faces yeah and so that’s what we want to say to the teenage brain one thing that we learned in our research is that the reason the brain changes during adolescence the reason you said that those changes help you become independent that the changes that your interest in the world that your interest in exploring new things helps you become independent from your careers and that’s important because if you are always dependent under parent or your teachers your whole life you would never take the jobs you

would never go travel by yourself you would never try new things it’s that’s why it’s really important your brain supports those changes it wouldn’t be healthy if my four year old daughter did the same thing that you guys did right because she’s not aware enough of the danger that could happen ever whereas teenagers are in a position where if your brain is started is mature enough to know what could happen right you can take care I mean you leave the house by yourself without your parents probably lose you because your parents know they have to take care of your body okay so what are the see is that so is that you sure you video a cartoon picture of the brain and obviously this is a brain compass skull this is insight on the surface of your brain where do I hurt right above your eyes is called the frontal lobe and and the part in the back of the brain is called cerebellum this is what helps you walk and do different things for you one of the parts the yellow part helps you see the pink part helps you process emotions and it helps you because the part of the brain is very active when you’re sad happier in any emotion and the front part of your brain is what helps you control your behavior so whenever you’re about to do something that you’re very excited about and it maybe might be somewhere maybe maybe not this blue part of the brain the frontal part of the brain helps you control your behavior as you control your emotions and so together the entire brain makes you an adult eventually once the last part of the brain mature do you think yes well it’s its function is to block your yes the reason that teenagers are more impulsive sometimes it’s because the front part of their brain is still developing and it’s not able to it is able to control dimples since the maybe not as often or me it doesn’t eat sometimes teenagers may not care in the back and that where the brain stress will be later now as we peel away the top layers of the brain we start to see that their region is my brain that are in rats are in yellow it’s a further brain called the reward center and it greens a part of the brain called out what it is yeah exactly it’s the feeling of satisfaction or pleasure or happiness that’s and if you get your fruit juice called dopamine dopamine is a neurotransmitter because no sensors or chemicals in your brain that get released for different things you neurotransmitter for reward me you have a neurotransmitter for sadness promotion sometimes called serotonin and all these different neurotransmitters help you experience different feelings emotions

behaviors and that it’s released in the nucleus accumbens is are in the yellow part they’re more thinner and reading art is part of something cold no this is so important for you to know hippocampus is bright new brain that’s responsible for memory and for learning all you’ve had many things your life that you only remember some of those things and the reason for that is because you to the campus which is the place where you store memories can only hold so much information and so some memories you forgot you don’t remember maybe what it was like in you or two years old but now that you’re 13 14 15 you have more memories but you can remember things better better and that’s an example of how the brain is developing from the back to the front because right about now when your teenager this is the focus the development of the memory system and the development of the reverse and both of those things help you become an accomplished because you are able to identify the thing that you find rewarding for some people not make you math my music whatever you find rewarding is what you start to do more and more up when you’re a teenager and that helps you find things that you were excited about the memory system of the first helps you form memories and that is what helps you learn the things that you are learning right now you’ll use the rest of your life something maybe not but moves you will how do you are thinking about going to university right some of you it looks like an x-ray similar in that it takes pictures of the body it’s similar to capstan you’re getting closer my customer spends its magnetic resonance imaging inner an MRI and the way the market works is that this is a person who works in my laboratory and that’s a child in our study so this MRI if you have a broken leg or something else maybe you’re there but we use it to take the truth of the brain and the reason we like it is because an x-ray is actually not very good for your body too many injuries but in MRI is not an x-ray what it does is we lay the person down to the bed itself and while the person is in the MRI we take pictures or rendering and the pictures allow us to see the shape of the brain the shape of the reward center in the hippocampus but it also allows us to see how the brain is working compared to younger people who put in the MRIs like little kids and older people like adults that we could in MRI and so then we see all the different pictures in compare them and that’s how we learned that the reward center is much more active teenagers than it is in children has anybody here ever seen an MRI scan or like those blobs colors of our brain you’ve seen before yeah the way it looks is that it shows up I’ll show you one in a second but it shows different colors of that light up in the brain and what we found is that the way to bring lights up during teenagers by the way this doesn’t hurt there’s nothing invasive about there’s nothing that there’s no

injections or anything it’s just laying them on the bed and we take pictures and you can’t see it here but this child up on top there’s the screen and he can see a computer computer screen on the top of there and so we show him images of emotions sometimes pictures of their friends because do you think that if you saw a picture of your friend and you saw a picture of a stranger that your brain would act differently yeah exactly accidently what because you know it’s this familiarity so your brain might actually be working hard in the few campuses it’s a memory it’s recalling the memory of your friend exactly so it’s gonna bring up maybe some feelings of reward yes you see that friend every day and and that will trigger activation and something called the face area you know that humans are the only creatures on earth that have a special part of the brain dedicated to recognizing faces it’s amazing I find that really fascinating because if I look at ten different monkeys I can’t tell them apart I can’t their faces all look the same to me but if I look at each one of you looks different to me and that’s because my brain the face area of my brain is looking at each of you and recognize these differences even though we all kind of look the same right all humans up most humans have two eyes a nose and a mouth so why is it that you can recognize different faces why is it that you can see your friend and right away nose you don’t have to introduce yourself every time right you already know and the reason that’s relevant for this for adolescents is because your face area becomes a faith expert when you’re a teenager right now the teenager you’re the best at recognizing faces why might that be why might we need to be really good at recognizing faces more teenagers you’re meeting a lot of people you’re meeting probably more people than you will in high school and in college you need a lot of people and so you we need to have a way our brain to be really good at recognizing people that we need the other reason is because mostly during the teenage years and and right after that people leave home people well maybe I don’t baby people leave home after like 18 or 19 it’s not you see most people when you turn 18 you say goodbye your parents you leave you leave your house no matter what whether you go to college that you’re going to work or whatever you do and so that’s another reason that maybe you’re really good at recognizing faces of age because you you start meeting people who are not okay and here’s just one experiment we’ve done so what we said in Reverse is inviting because I think most people like money so we showed people money and there’s a little summary and it’s that activation that I was telling you about before that Neville part of the brain is the reward center and that lights up when people see money it actually see first agreement like but yeah compliment that’s really really good that can’t really be some experiment where people people used to just be people money well they got their picture of their brain and then people gave people like juice while they were like all their rating that MRI we had a straw and we gave them drops of juice and that’s where the same pattern we’ve also shown people pictures of their friends and that shows the same accusation but when we give you a compliment that’s actually with activated the brain and most that’s what teenagers at least in our setting find more rewarding than money or the faces or the chocolate producer we’re complements is very meaningful 50 majors and all of this is to say there’s been plenty of is because your brain treats every single reward the same way there isn’t a part of the brain that deals with money or separate earn the brain that deals with food it’s all the same

part of the brain your brain you very word system responds to other words in the same way what does the pedigree words at any art so therefore you might activate actually what else I’m thinking about things that maybe are not good for your health smoking drugs alcohol they fit it’s a statement ring because your brain doesn’t have enough room to have different parts respond to different reports and sometimes you start you guys know that some people suffer from addiction right it make sure it’s nicotine addiction to top the addiction drugs that addiction happens because this curve the brain keeps getting active it keeps watching more of that same drug or alcohol routine or whatever it is all of that happens right here in the center of the brain that also responds to money even to compliments and so actually one reason that scientists have found that if people start smoking when they’re teenagers or started drinking when they’re teenagers it’s much her to abandon that addiction because if it happens when you’re a teenager your reward system is already very active and so introducing nicotine or or whatever it is into this brain system makes it further to abandon the addiction later does that kind of make something it’s gonna respond to those ok so here’s just some um data you get a lot of bar graphs so this is a bar graph and on what this is showing you is activation of the brain but remember that we studied three groups of people kids young teenagers and adults and so that we put their information their data on a bar graph where we measure the activation in the brain we know that everybody showed that the ignition in the brain even the kids when they get money but we what we show in this bar graph is that the teenagers in orange have a higher bar and that’s representing the greater activation in their brain compared to in compared to adults but there’s exaggerated activation in the teenagers ok so what’s good about brain changes about happen during the teenagers I’ve already told you the independence the exploration learning all those things are really really important but one thing that minorities been a little bit is that teenagers are really good forming social relationships why does it work to be good at forming social relationships or carrying out social relationships you don’t want to be alone yeah our species depends on the fact that we want to bond with other human right other animals like that too late monkeys are very social creatures but humans are the most social creatures on this planet and that means that teenagers have very different jobs of learning how to have good social relationships and it’s for that reason that teenagers listen a lot to their friends how many of you maybe like spend more time with your friend versus your hair so what I used to feel like that too I used to want to spend more time around I found my my friends more rewarding and we did a study to understand why is it that teenagers by their friends were rewarding here’s what we did we asked you majors to come to our lab and a video game a video game where they they were in a race they were trying to get to the end and they were asked to drive very fast on the computer game but every one so I wouldn’t see a yellow light and what happens when you see a yellow light you just look at it sometimes people speed up because they try to run for the light right and so in this game if you read the video like that was a risky choice sometimes it makes me crash again sometime

and we asked people to play the game by themselves or to play the game when they brought their friends the laboratory and when people brought their friends to the laboratory did you think that after the same as when they were results now what happens when you’re around your friends you take more risk yeah well we didn’t know that we haven’t but yes we found that people take more risks even even on the game that’s just on the computer screen even only game that means nothing people take more of us what else have to be around here yeah teenagers some teenagers laugh more the behavior genius like if I’m going none of us like this room you guys are be acting very differently right and that’s teenagers ask you something about the front makes their brain change how they behave it’s a usually fun so we found that things on the graph I’ll just explain it quickly when people were alone it’s they ran the other leg got half of the time no matter if you were a teenager a college student adults but would be happy friend in the room now that red bar with the arrow is showing you that teenagers took many more risks when their friends were in the room whereas all the students and the adults didn’t change their behavior and so that suggests that there’s something about the friend that changes how the brain is thinking this is the last rap I’ll show you that reason that happens is because the activation than the reward system goes up when the friend is in the room so that means that the friend is acting like a reward and that reward is making them take more risks like if you’re out with your friends on the weekend are you more likely to seek out risky behaviors or do risky things with your friends yes and our D is suggested it’s because of the reward system that gets more activated in the presence of your breath so the last thing I want to talk to you guys about is something that you also do to stay in communication with your friends but when you’re other women at night you guys are you friends any yeah right before bed yeah okay and your parents tell you to turn off the funk yes why it can be bitter they want you to do it and why do we care so much okay that’s good finally get my soul I said vio settled uh samosas which I’m gonna eat what esle when you’re asleep your brain get the chance to rest it gets a chance to form the memories and work on the campus and the problem the problem with the phone well two things one is that it’s very normal for teenagers to sleep less than their younger siblings and the reason for that isn’t just because you’re on your phone it’s actually because your brain doesn’t release sleep hormone at the same time when your teenager so for example there’s a hormone called melatonin maybe you’ve all heard okay melatonin when the Sun Goes Down your brain releases something called it’s a chemical called melatonin and that wouldnt helps you feel sleepy when your teenager melatonin doesn’t get released into like ten o’clock at night and so it’s hard for you falsely even even if you’re not looking at your phone but if

it’s not sitting there looking at your phone makes it hard to sleep because your phone your iPad liver releases something called blue light you know that the screen right blue and blue light it’s similar to some light and so when you’re looking at your phone right before you go to sleep your brain is tripped it’s under music trick its deceived into thinking that it’s daylight and hues are really good at being alert Wednesday be alert keeps you safe right if you if you were always walking around sleeping you wouldn’t be aware of a threat in the environment right if you were an animal you might get killed by life you’re not paying attention and so it is daylight outside your brain thinks that you should be awake if the brain thinks that this phone represents daylight then it tricks your body to be more alert and you wake up and so that’s my parents their kids to trim to come not because the phone not only gets you kind of a wake because you’re coming your friend laughing either maybe you’re feeling emotional for something your friends are calling you but it’s also tricking your brain it’s a way to turn your phone into you need it in getting a different kind of light okay the reason I was greeted is to avoid sort of blue light what if it’s like orange red wavelengths that don’t treat your engine okay show you one last thing so we found that people who have poor sleep brain development is getting you’re a teacher and we were raised to stated what causes people asleep not just the phone and we measure it’s a very big city there’s some parts of the city that are very wealthy it’s impressive the city that are very poor okay it’s a mile attributes of different pulses here’s the house of a child in Beverly Hills they have a very big room they have a lot of a nice bed the bathroom here’s a child lives in Compton Compton is not a very necessary Los Angeles it’s crowded and they share the room that share the bed and we were interested in determining whether having a different sleep environment makes that Burger to sleep which room music wouldn’t lead to better sleep we were wrong that’s actually didn’t matter it didn’t matter the room the one thing that mattered there’s something there’s something in these rooms one thing that makes a difference for how they sleep look at the heat the temperature we thought that we didn’t know the noise in matter some people live in bad areas where there’s a lot of helicopters anyway that’s a matter that everyone could have access to and that’s the number one thing so the type of pillow you have how do you like your pillow if you do not like your pillow tell your parents today to buy you a pillow because your pillow makes such a difference for how long as you sleep it’s even more important than how much time you’re on their phone it’s even more important than how much noise is in the house your pillow is what helps you have a good sleep and will be found if that kids you have teenagers of of good sleep well good for us who gets asleep I’d better bring it on and are better able to learn at school the next day if they’ve had a comfortable night of sleep okay so I think that on this bed do you guys have any questions on any of that it give you a lot of information you have questions

I know you do teenagers are always more quiet than never gained anything not even yesterday the kids want me to talk about dreams a lot what are your dreams friend Harriet conflict roughly hormone and the dopamine is like the why the draws are yeah okay from yoga understeer and Todd’s life and so when you take a drug the nicotine makes your brain release dopamine the reason some have you ever wondered why some people become addicted to cigarettes and why can people do not the reason is because some people who have a more addictive behavior their brain releases more dopamine when they’re smoking it’s nothing they do or nothing you’re just born up some people release more dovish they have a bigger drop and some people they smoke a say I will give you cigarettes and a portion of the teacher and I didn’t like it all that leaves my great release a lot of dopamine but the people whose brain release a lot of dopamine you know when you let they can you start with the Anders the next time you might release this much right and then the next time maybe this much and so eventually you’re like I really like doing that but what happens over time is that eventually in order to get this much dopamine you need to give the brain more more of the drug than you did the first time because you’re so there’s something pumps hollering yes yes your brain gets used to use obituaries and so that’s what leads to the addiction this behavior that even if you don’t like getting work your brain says but you gave you this one time and it’s great that first time and now I want that again and so that’s what diction happens but for some people they may be negative but don’t like alcohol or something like that and that’s because their brain everybody’s brain is a little bit different and we release dopamine in response to different things and it’s the same reason that some people like Heights some people like you you look at whatever it is that you like it’s because high your response back yes so dream scientists want to know when rings are because dumb dreams are cyclic some dreams are like one of the cat that means ever-present mom it also but sometimes breeds just represent the memories at injury yeah so these times your dad away when you’re sleepy your brain is making those memories it’s making a memory with that for that and that’s what you drink about the other thing that happens that it’s not about the dreams that you have or the people that you’re with it’s a thought that you have so sometimes if I so I’m in Spain and my family’s in Los Angeles right now and I think a lot about my carrots so even if I’m not with my parents I think about them and I can dream about them at night it’s just it’s just a representation of that would be really interesting it would be hard to do but the only problem would be that you have you can’t control people scoffs so even if you do the same thing every single day you’re foxy pretty different every single day even if you took someone who’s in prison and they’re doing the same thing every day between prison their thoughts are going to change your questions about the US about college in the u.s. there are sometimes

about drinks and predict the future like you have a visual and why we don’t have no idea what happens what might either we predict the future in the sunset we’re thinking about what we want and that thought creates the dream and then eventually that leads to our behavior that caused the best happen but it’s really hard to understand why dreams can be prediction sometimes yeah emotions are probably the most powerful thing emotions affect our behavior emotions affect our dreams emotions even affect our physical body have you noticed that I mean your feelings that you may not notice but your body actually kind of kind of goes inward and people who study clinical psychologists study depression for example they think that the reason our bodies changed and we’re depressed is because it kind of shoves our body down a little bit it means that we’re not in a good place to behave the same way and some people who feel depression sometimes even feel sick like they physically feel sick and that’s because of the emotions the emotions lead to change why we don’t remember bowl of drinks without writing or yeah why because that campus that part of the brain tissue – it’s actually not very good okay raising up everything’s right they have to fit into our skull into the actually this big and that part of the brain is all your memories from your whole life and so when we’re sleeping our brain actually kind of start sorting through the something that lives in the trash some memories never get formed because they’re not 40 or because their aegis capacity it’s a week during oversleeping sleepiness will be important for establishing memories and for remembering these it’s also an important part forgetting you forget a lot of good memories you make during the day get thrown away at night and that because you don’t have the space in your brain hold on every memory it’s the reason we don’t remember things from before about three each and most of the things that are happening before age three or four are or what what are we doing during that time we’re learning basic things were burning on the top we’re learning how or parents are so all the skills we don’t need to remember how we learned them and just know that we’ve learned that you forget you forget along because the memories number is strong so I if I walk out I’m gonna go to the store right now and then walk by sorta yeah it’s because the memory is kind of loose but the thought was loose it wasn’t a very strong thought whereas if we distract ourselves – so let’s say you say I’m gonna go okay you can bring to your friend and your friend elicits emotions in you and then you just forget the reason that thoughts that are not very meaningful or more easy to forget but thoughts that are emotional are very hard to forget our memories are very closely tied to emotional events so if you are you know your good friend using a car accident on the same day that you have an exam that’s going to be a very emotional that you will probably remember what time of day it was in that car accident happened what you were wearing what your friend was wearing what what the last thing you said that person was that memory is very strong because the memory is tied to the emotions whereas you don’t probably remember what your friend wore the last time you saw her two weeks ago maybe so emotion help us build our memories

that’s why you look at the experience when you hear song and it reminds you the place or you smell you know I can still smell particular Cologne and it reminds me of my first you know like it just it doesn’t it’s so powerful how emotions are related to smell insecurity into all of our basic sensory yeah I suppose it the brain is a muscle yeah so how can we as teenagers it’s great this muscle yeah it’s a really good question so one is learning languages because if you’re giving your brain a challenge but it needs to practice it’s the same way that if you are really going to play tennis or soccer or something like that practicing it makes you better at it let’s take you to the brain and the way we practice our brain and things that are not a specific skill is to is to give it a lot of different new things to try and so that’s my exploring new things but for teenagers to practice learning new things in in the brain so simply experiencing yeah I know yeah so the question was why teenagers are better able to learn things and the reason is because back with the campus art degree works that actually in your teenager it works faster and so it takes you use less time to learn the same thing that it takes an adult the reason for that got one your brain is still plastic it’s a term in neuroscience that means that your brain is still open to information it’s malleable it can move and shaping and the reason that adults become less plastic in their brain is because at some point our brains need to become stable and if your brain was plastic your whole life you would never be able to become an expert in anything does that make sense like if your brain was able to incorporate language your whole life you may not become an expert in any one language right like my primary language is English but I speak Spanish because my father grew up in Mexico and I learned Spanish another kid but because it’s the English more I know how to speak better English is the same with all of you but if I was able to learn every single language of the world in the art room I’m going to focus on one language to the next it’s the same with everything else if you practice a lot at tennis you’re probably going to get very good at tennis it’s going to make it harder for now now you can dream about strangers but these people who are strangers in your dream if there’s a good chance that you saw that person without realizing that you saw that does that make sense sometimes when you’re on the bus you see many many people and you’re not really actively thinking about who they are what they’re doing but your brain is noticing and sometimes your brain drags on a random thing to your brain is always working even in their sleep especially yeah strongest when your teenager as you get older and you start forgetting Network and we’re probably the reason is because that part of the brain actually starts to shrink as we over and someone yesterday asked about Alzheimer’s and what happens when people have all centers is that that part of the brain basically stops working and so they can’t make you memories they might remember really old memories but they can’t remember really like their keys is

mine now there’s some research to suggest that there’s some genes genetic material that makes some people more likely to develop also but there’s other research to suggest that people who stay here and active their whole life in terms of practicing their brain things may help dam in the effects of all things but it seems to be genetic but it’s not there these are challenge is that people now and this time are our species live longer than they used to so in many generations before people would die I think the average life expectancy was like 40 and so maybe those people would have gotten Alzheimer’s but we don’t know these in diary whereas now people live United States so we’re living twice as many years and so maybe that’s just a condition of the human brain that we can’t oh yeah the person has ELISA nations you guys know loosen Asians or you either see things or you hear things that people know and that’s that neurotransmitter dopamine that I talked about before one thing it does is respond to reward but don’t read a lot about this institute and one thing people think is that people who have schizophrenia have too much dopamine and that the dopamine creates these hallucinations in the range but it’s unclear what the other mystery about schizophrenia is it the majority people who have schizophrenia do they have it when they’re three years old or four years old when do they start I mean stupid they’re showing us interpreting teenagers a lot of mental health issues arise and continues that’s another reason people want to understand teenage brains not just because we don’t understand why teenagers make choices that they make but also because the majority of mental illness if you’re gonna have much illness the majority of the arms that happens between the ages of 15 and 24 that includes schizophrenia depression of the OCD OCD anxiety and eating disorders those are those are the majority problems that happened so why what what is it about the teenage brain that makes these things come up some people are make probably born in these conditions they don’t exhibit their condition and one idea is that maybe all the emotions that are so strong between this brain might make these conditions more apparent yeah yeah so that emotion feminine brain part of it helps you recognize reward exactly the other part of it is important for recognizing threat and soubrette we’re really good at every species in the world you’re an animal in the wild you hear noise it might be alive so you look at you look at if you’re a human we’re afraid to be hurt and so the emotion Center that recognizes fear or that helps you feel fear is very active especially when you are kind of you know feeling emotional if you are getting your love you’re already a little bit kind of aware of your surroundings right but fear to be there to be negative but here to make you do not do things fear that you can limit you but fear is also important to to make you sure that you stay

yes please video game effective rain the American Psychological Association has very big study on this and found that well what do you guys do video games her memory okay so they study thousands of teenagers and they found the answer was that they found that video games does not hurt your brain may be not there there is I know I chose Santa Clara because we liked the size of the school and that was primarily it
