Our Ever-Changing Brains | Kimberly Carraway | TEDxSamfordU


growing up and what I do now going to

spend some time that I learning about

learning steps a good after Birmingham

Alabama I’m the oldest of five kids and

I wanted to be a teacher from day one so

my dream it was teach school so it’s a

little bit all that with lamb all my

stuff and you did this but lead officer

vehicles now and I made them all and I

got a dad take me on my mom to take me

to parent-teacher store and I would get

a grade book and I could work books and

I photocopied them yeah you better teach

school tomorrow stuffed animals and I

thought your school I’m going to copy

those pages and I love filling help and

handouts and appropriately or you know

correctly so that I could grade of all

of their work and so I had this little

great grade book and in every grade book

you can see up here that I wanted a name

I have lesson plans for where my kids

were going to sit and then I would of

course all the people in the

neighborhood to come down to Jubilee

school after they were peaceful and this

was something I found from of 1983 when

how its testing everybody on their

ability to swing that they’re swinging

muscles so I gave my sisters you know

scores and all the kids in the

neighborhood so from day one that was my

goal I wanted to teach I wanted to grade

papers I wanted to you know change the

lives of children

and so I felt I ended up going to being

a vote for college loved being in school

there were no plot from books about how

to teach and how people learn and so

then I started teaching school and

that’s home-school out of us oh gosh

people learn really differently like I

would teach a really good lesson about

less than I thought and in really good

job teaching and some kids would get it

in some kids play and why did this can

have trouble learning as multiplication

facts but this will croak didn’t and why

is this little kid have trouble reading

and what is this one not and so I became

really fascinated and learning about

learning

I wanted to know okay so we have a brain

and I had heard it was like a memory box

of the bread right I’ve seen these

pictures of a file box and I thought

okay where is my pile box how do you get

something to fill in a memory stay there

and then retrieve it on a test right and

I figured well I’m afraid of that I’ll

then I could be a really good teacher

and help kids learn in school so also I

was growing up I should tell you I’m not

a great speller like and people don’t

believe that sometimes cuz I went to

made a Bolton Harbor but like really I’m

a really bad speller so growing up I

always wanted to be in an Honors English

class when I was in high school so I was

also not a very leader so it is not like

me

not actually meeting better not enjoy

any time I’m thinking actually feel

honest and so that I was always forced

readings for school and I didn’t want to

be an Honors English that was like a

goal that I have and it must would never

let me in daughters Englishman has my

PSAT scores were too low the venire do

experience out how PSAT score and

reading comprehension was never high

enough to give me $1 English you know

how to ace in English and so from that

point I felt by those standards tests

are really this definitive measure of my

intelligence right I thought if you

wanna kid it works really hard I can’t

spell but I’m not really that smart

because Bose that smarter which really

want this test and that was my view of I

you know how different Elgin you would

see that on the test and so as for mine

I did get in beautiful winter school

then I’m going to Harvard for graduate

school and love being there and as I was

there I learned a lot about how people

are and so at Harvard I still was a

really bad speller so this was on the

cover of my notebook let me show you

where I studied about how people learn

and how there are variations in learning

and I was still a girl

they’d like to do bubble ever tried to

load all the bubble letters and I’m

actually little meta books and I don’t

know if you can see it very closely but

this is a class on learning disabilities

that I spelled disabilities incorrectly

all right and I have a heart for people

struggle in superheroes and so what I

repeating in the study was how do people

learn where is memory where is that box

that was what I wanted to find out and

so we’re going to talk a little bit

tonight just as awful right you’re going

to get a mini course in about six and a

half minutes on the to the brain and how

you work because what I have learned is

that learning about learning can

transform the way that you do school it

can transform life and also what I’ve

learned is that there are so many things

that we believe to be true about how

learn they’re not actually true we

haven’t had an explosion and filled with

neuro socks and in education and in

cognitive science we have technology now

that lets us actually peer or below the

surface and watch the brain at work in

real time so we grew up with all sorts

of theories about how people learn and

now we can see pictures and images of

what’s actually happening in real time

so this is a diagram of the human brain

I are looking at the brain from the side

and nice made up of two parts two sides

if take a fist and put them together

like this we’re going to interact in

theory all right all right so you’ve got

right except you bring your left hand up

to your brain she’s onto your back

you’re actually in our

graduation from rioters left in

depression from the left goes to the

right people who are believing that

there is a theory that we believe to be

true called the something we refer to as

being right right or the left brain are

going to be heard of that theory I guess

what no research to support that I

they’re not right rating with what

electrode you have a right side to the

right you have the left side to the

brain but that theory incinerates did

you use only part of the brain when you

are learning or any other strength and

one saw the brain over the other truth

is you use most of your brain when

you’re learning to do all sorts of

different things I see how this right

chemistry have this left chemistry and

they work together and so we think of

the greatest we can make an apple all

right so an apple has a core structure

in the center and then you’ve got some

bead around in the you’ve got this

didn’t layer that’s on the edge of the

Apple like the skin all right to the

brain is similar down this course

structures deep in the middle now we

have this outer layer that’s called the

cortex and in the image

going to show you up here we’re going to

look at how different parts of the brain

do different things alright so as we go

through those restoring the back of the

brain so in the back right here she came

to the bottom of your head this part

right here this is actually where you

process visual information alright so

when you’re looking at pictures when

you’re looking at the keynotes thoughts

from your professor when you’re checking

out images on Instagram when you’re

picking out clothes to wear for the

party

you know any visual image is going to be

processed and actually stored in this

kind of brain I maybe close your eyes

and you picture something you’re

daydreaming in class even if your

specific taking notes but you’re

daydreaming about something where you’re

replaying a play from your intramural

football game all of that imagery is

occurring in the back of the brain

I had activated to the side right around

your ears you have the cortex it

processes auditory information I so

auditory information anything that you

hear anything that you say inside your

heads yourself language music you know

your Spotify playlist when you’re

listening to that it’s all happening up

here you’ve got brain cells and they’re

firing and they’re networking together

the teachers lecturing in the classroom

you’re listening to that lecture that’s

getting processed on the right your left

side of your brain the triple loop I

have a toughie braid this section is

called the parietal lobe and the

parietal lobe is responsible for spatial

awareness so your ability to play Tetris

right taking

make rope chain fit into something to

pack the back of the car Japan minute

carry-on suitcase you gotta pay the

extra baggage fees right any of that

ability to mentally rotate something and

do something with it

the front of the brain is referred to as

the frontal lobe I to take care of the

race forehead like this is your fruit of

why this part of my name is the part

that is like the CEO or it’s the

conductor of the orchestra it is

basically telling the other part of the

brain what to do when to do it and what

order to do it it plans

it pays attention it zooms out it is

responsible for saying don’t do that

stop looking at this to finish the math

homework if you got that pencil

maybe it’s directing and hewing behavior

that’s occurring in the back of the

brain either follows or the part of the

brain that you don’t want damage any

part of the brain but you really don’t

want to damage the follows because the

frontal lobes are what the conveyancer

and so let’s think of the brain almost

looking for mistre where we have

different parts of the brain that jun

different things and so when you’re

reading your science test book we’ve

let’s take a corner section playing and

we’ve got the winds going and we’ve got

the piano playing we’ve got drums and

then when you’re doing math problems

you’ve got a whole different set of

instruments that are coming online

together to perform a certain function

and so the scruff of the brain is the

one that is coordinating all of that

activity if you are toning out

my ass is the front friend range that is

responsible for that I am this is the

part of the brain also it doesn’t finish

developing until your late 20s all right

28 29 30 so we used to believe that

you’re born with a certain level of

intelligence that intelligence was

pretty much fixed like you’re one that

way that’s what you got you know just

could I we just invest with what you

have all right that’s what I believed

when I took the SATs when I took the

PSAT but now through all of the research

from the fields of neuroscience colors

that’s what we learned as if

intelligence is not fixed the brain

actually changes as you grow and it

changes as a result an experience so I

can literally every single experience

that happens in your life changes the

internal architecture of the brain I

mean that’s pretty cool right so even

when you leave this talk your brain is

going to look a little bit different on

the inside than it did before you walk

down the door after Netflix near harm

right it’s going to be different at the

end of that all right Oh after you go

all sweet like it’s going to be

different all right brain changes from

every single experience for good or for

now and the cool thing about that as

intelligence does not fit because you’re

born with certain genetic coding but

then experience is what develops the

internet works of the brain so if you’re

not reading spelling like I wasn’t great

in spelling and I had

of opportunity to get the right type of

intervention and the right type of help

when I was out there then I could have

actually strengthened that part of our

brain when we look at the brain think of

it as this Orchestra of activity all

right so when you’re getting ready for

your final symphony and you’re thinking

about okay I gotta get ready to study

for these tests think of the brain as

having this Orchestra that is playing in

different regions so my question when I

went to Harvard that I really wanted to

know the Institute was whether it is

that memory box okay like where is it

physically I’m saying like no I want to

know it is it here is it here is it here

and like what we do to put stuff in

there by you can you compute that at all

put all the information in then then you

have your final you can retrieve it when

you take your test turns out there’s not

one spot remember there’s not a box in

which you know we get into all right

memory is actually distributed

throughout the brain so you have

billions and billions right notes after

shunga right now if you’re kind of

curious on 86 billion if you’re an adult

and you’ve got all those brain cells in

there in those brain cells fire and

network together and so when a certain

group of this brain cells fire together

when you’re learning something like

adding fractions

they are very fragile you’ve created a

brand-new network for how to add

fractions I you think you get it you

understand

you get home you try to do your homework

and add fractions and guess what you

forgot how to do it

all right and that’s because the network

is really really fragile the brain is

designed in such a way that all of these

brain cells and we’re talking billions

of them the way in which they

communicate is that one cell gets

activated and it sends a signal all the

way down along axon and as it comes to

feed into the axon it spits literally

spits out neurotransmitters and as a

next cell actually there is a parking

spot for those neurotransmitters parks

in there and then takes it on that

activity and activates the next cell now

using a lot of really big words that I

did not just use that’s how nervous

conscious would explain learning okay

we’re one cell fires and then another

cell fires in response to the first cell

fire and so when you are learning

something you literally are making these

connections in the brain and that when

one fires the other one starts firing

him then one fires that fires again as

it ours a little bit faster that’s when

we know that learning has occurred the

interesting thing about the brain and

how these Souls have networked together

is that you have to require these cells

a certain number of times in order for

it to remain active in long-term memory

so we can actually move anything into a

box what we do is actually refire the

network that was created originally from

the experience so if you’re sitting in

class and the teacher is teaching on

something about World War two and you

have this real

yeah and you’re so into the bed right

and then it clicks really cool oh it

smells pretty too we all look at a boy

if I look at this way I look it over

here right you are so into the pen

teachers teaching a wonderful lesson

about World War two all right you leave

you try new homework you may not

remember anything that was actually

sellable or two because if you are not

paying attention during the learning

experience then it’s not actually going

to make a network all right what will

you remember the dip right here you have

a great network for the pin you’re going

to have memory and a taste part if you

licked it if a small part of you spill

it

lots of time talk with me you’re going

to have to be distributed across the

brain and wonderful lower about the pin

and so attention is going to dictate

what gets saved into memory and what

gets laid down the cool thing about this

is that when you sleep this information

that you’ve learned every day the

experiences or the networks that you’ve

made during the day guess what they get

me fired

over and over and over again during REM

sleep

that’s the rapid eye movement parsley so

that’s actually when you’re dreaming be

a wandering cycle every 90 minutes

all right so during that dreamy part

sleep your brain tonight if you get back

minutes of sleep it’s going to refire

those connections over and over and over

again and that is what is going

as those connections stronger and then

tomorrow 24 hours later we’re going to

know what remains active in working I

mean in your culture program so high as

we apply this to being a student all

right I’ll give you a few takeaway chips

there all right that I think are really

really important to know in terms of how

we can use this information from the

field of neuro education which is last

day and that’s the translation of

cognitive neuroscience into classroom

practice and so here your 3 top tips are

you ready

number one sleep all right you need

sleep

all right so fun to go out someone to

have a great time but sleep needs to

follow learning what you do right before

you go to sleep at night little implied

before you go to sleep at night is going

to get priority and being stored in them

right so you’re studying for your test

what I want you to do is study earlier

in the day pull out your notes review it

for 5 or 10 minutes before you go to bed

it will actually help store that

long-term right center figure would you

remember is that memory is distributed

all throughout the brain so students who

income what they’re learning physically

in the back because they have visual

imagery on the side because they talked

out loud while they were studying on the

top or motor movement is because they we

copied their meds they physically have

more places in the brain that represent

that

and they have more ability to recall it

later

and the third takeaway too is the way

something stays active and long-term

memory is you have to review it over and

over and over again it doesn’t have to

be direct repetition but you have to

refire that network so when teachers

tell you study a little bit each night

and then like number your does it right

reason and I don’t even know that they

know why I told you to do that but the

some tiffin reason is literally five

minutes of review one day not like 45

minutes which is five minutes it’s going

to refine those networks and while you

sleep it’s a coded into memory and then

when it comes down to setting and are

going to have to study as much at the

end so I encourage you to dive into this

field of neuro education if you are

interested start learning about how you

learn and how this can impact what you

do as a student and I want to encourage

you that intelligence changes and brain

changes as a result of experience so

there’s something that you’re not great

at doing and you really want to become

better at doing that you can’t and if

you take the different experiences that

are going to improve theirs every senior

brain literally next year at this time

you can have a marriage of a brain you have today so thank you very much
