Synesthesia and the Connections it Makes | Noelle Hanson | TEDxLAHS


there’s the story my family likes to

tell me when I was about two years old

sitting at my grandparents dinner table

and pointing excitedly at the window

saying cat over and over again despite

how hard everyone tried to find the cat

that I so clearly saw it took about two

minutes for them to realize that it was

just a shape in the window created from

how to trick the curtain straight it

wasn’t long after that that my parents

began to noticed that I visually picked

up on things that they failed to see

although I couldn’t even remember the

names of my closest friends until mid

grade school I could describe everything

that they wore that day or find specific

facial features that two unrelated

people had in common as I made my way

through school I realized that my best

note-taking strategy was one that

involved colors and diagrams and

pictures by the end of the lesson my

paper would look something like this and

these are pretty mild examples I

remember telling my mom that I learned

better when teachers dressed

interestingly or when with colors and

accessories or when they used two or

more colors on the whiteboard

I noticed the smallest visual details in

my day-to-day day-to-day lives like when

someone cuts their fingernails or the

computer screen is a little bit cleaner

than the day before

with such a visual brain I’ve also

experienced many challenges in writing

math and conversational skills I’ve

often felt embarrassed about my work

which meant that I was less likely to

get the help that I so desperately

needed in middle school where I

frequently found myself in the middle of

large groups with multiple conversations

going on

I found myself one beat behind and as a

tall awkward tween whose ears stuck out

a little bit too much this proved to be

really difficult especially as

friendships began to rely more on

conversations and rather on shared

activities especially during this time

was when I fell in love with dance my

ability to express myself using my body

and visuals rather than just saying

things these challenges let me reflect

on and explore what was actually going

on in my brain and through some research

I found that I have a rare condition

called synesthesia synesthesia is often

referred to as the blending of senses

such as one’s hearing sight or taste as

dr. Veronica Gross from Boston

University explains it is synesthesia as

when a certain part of the senses

activated and then another unrelated

part of the sense is activated as well

around one in 2,000 people one in every

two thousand people are estimated to

have synesthesia and it’s thought to be

caused by the hyperexcitability of

neurons in the primary visual cortex

this results in some people tasting

colors or hearing sound are seeing sound

and for me this hyperexcitability of

neurons in the visual cortex manifests

Met manifests in almost every number and

color having a corresponding way every

number and letter having a corresponding

color and personality before knowing

what synesthesia was or that someone

could be a sinister I thought this was

how everyone’s brain worked I thought

everyone knew that the number three was

green and that the number eight was a

purpley blue and the eight hated the

number six and seven I thought people

knew that my name was a pink lemonade or

sometimes a lavender but if you take out

the extra Ellen E it turns into a

completely different color I assume

people chose their favorite numbers by

choosing the ones that had the most

interesting color

so naturally mine’s 57 because it’s a

perfect blend of orange pink and red it

reminds me of a cartoon desert or family

road trips to my grandparents house I

didn’t realize that in an image like

this doesn’t make everyone’s skin crawl

because the number two isn’t red it’s

yellow there’s not an abundance of

research on synesthesia but what we do

know is synesthetes are obviously highly

visual people

synesthesia can be developmental or

acquired which means you can be born

with it or you can experience it in

certain situations it’s found in

families its genetic and has a pattern

Mendelian transmission scientists the

oxford university figured that with

individuals with synesthesia required

far lower levels of stimulation in there

to see streaks of light in their vision

so basically the amount of stimulation

it takes for your brain to react to

something is the is your threshold by

using electric currents in parts of the

brain researchers came to the conclusion

that because synesthetes have a

naturally lower visual threshold

easier for neurons to be fired and then

correlate with another sense or

experience when I began to understand

the unique way that my brain worked I

was able to experience more self

compassion for areas in which I

struggled in I was no longer embarrassed

by my writing skills knowing it wasn’t a

reflection of my intelligence but simply

a skill set that I fundamentally

struggled with this new information

helped my parents learn and expel my

parents understand how I learned and

experience the world in fact as I was

talking my mom about synesthesia one

night my dad chimed in saying that he

experienced the same thing too and we

figured out that he had synesthesia as

well it was a profound realization that

to my mom after 20 years of marriage she

never understood that my dad experienced

the world in this way and it turns out

he sees his day like a movie reel where

each scene of his day is depicted with

extreme visual detail so when asked a

simple question how was your day he’s

required to sift through massive amounts

of information and then translate this

information into words this process can

make his response delayed sometimes

which can be frustrated to both him and

whomever is listening because of this

conversation with my parents my dad and

I created a closer bond and my mom

someone’s whose brain works more

verbally was able to understand how we

interact and experience the world with

my newfound understanding and compassion

I began to be okay with where I was with

my writing and conversation abilities

and gave myself permission to make

mistakes in my attempt to improve

because the people around me understood

me better I was no longer apprehensive

to share my work knowing that they’d be

patient and appreciative of my efforts

over time I even began to challenge

myself I understood the importance of

being able to communicate clearly in all

aspects of my life so I decided to take

AP language as well as journalism as a

way to strengthen my writing and

communication abilities neither of these

classes have been very easy for me but

with hard work teacher and editor

feedback and support I found growth

growth and success and ways unimaginable

to my middle school self our natural

assumption that we all experience the

world in the same way as a barrier to

progress understanding and connection

sure not everyone has a random hard to

pronounce neurological condition like

synesthesia

but all of us have something unique

about how our brains work maybe you find

that you’re an auditory learner or feel

most comfortable when things are

explained to you out loud maybe you find

that you need absolutely zero

distractions when you’re doing your math

homework like music or noise or maybe

for you biological systems are best

understood with the video all of our

preferences strengths and areas of

struggle are valid and should be

encouraged and we should encourage

others to address them in the most

non-judgmental ways as possible knowing

that what if we all started having

conversations with their friends and

family about the ways our brains work or

how we experience the world how would it

feel if our teachers understood us each

on a deeper level

how what if we saw our perceived

weaknesses in the context of our

strengths or solve them as um sell them

as opportunities rather than obstacles

taking a few minutes to think about how

your unique self can be the key to your

success in the future try it when you’re

driving your car or brushing your teeth

think about the way your brain works and

how you experience the world and then

reflect and then once you self reflect

you must share these findings with those

around you like I did with my family or

my dad did with my mom

keeping these poor important self

discoveries to ourselves might cut us

off from benefiting the from the way

that our brains work once you do this

you might even be surprised about what

you learn about yourself and those you

care about

you may even be surprised about what you

accomplish once you know yourself better

thank you
