Et si nos expériences s’imprimaient dans nos cellules ? | Céline Guérin | TEDxGeneva


and if biology and psychology were

the two faces of the same mirror

all look like a parent a fingernail

a grandfather so we know that our

genes influence they have on our

behaviors but conversely

could our behaviors

change the expression of our genes

so these questions says neda who have me

always passionate because in fact I

wondering how much do I

am free to be who I want or

Well, I’m a little prisoner of his

question of heredity

so to the question who am I

nietzsche responds to us become what you

es

in reality it’s an invitation we

overtakes and free us and to express

which makes us vibrate then

personally what makes me vibrate

it’s the living is the human being

it’s trying to understand being

human is not always obvious and

then for example very young I

always knew hard to understand

why are two individuals who

live the same event are going

interpret it each one in a way

very personal

and we can remember at all the same

thing another event me

deeply inspired and to steer my

life most certainly because at 11 years old I

lost my fourth cousin of the

same genetic disease the

cystic fibrosis and I slip him is a

secret poem in his jacket in which

I made it a promise that of

dedicate my life my energy for

understand genetics understand

what made health and

illness and especially help people

suffering

so that’s what I did I

decided to study biology at 11

years ago I did my whole life program

I was all planned up

35 years old and is just before my PhD

as I asked myself the question is

what this experience ultimately goes

define all that I am and what

I would have made another choice

without this event is finally the

answer to my question I would have

studied the brain because that’s it

which interests me to understand how

works so I did a doctorate of

neuroscience it’s been years

exciting I learned there was

necessarily many things I handle

they live by growing my

small cells in culture

I played with the dna I had oreca

at 4 am to put together

the different pieces of the puzzle for

understand how these cells

works frankly it was exhilarating

but I finished this experiment

exhausted and a little disillusioned I confess we

warned me it’s the disease is

classical doctoral students I had trouble

to believe but that’s so I took

a few months to think about the

next because finally I had

still not answered my questions

and I needed to expand my

backgrounds

I needed human contacts and

by chance or by chance I met

a woman who offered me to work

in a psychiatric institute

so here I discovered a whole world

completely new because I who

knew the disease the suffering

physical I discovered the suffering

psychic

I discovered how these individuals who

had lived terrible things that

had lacked love had lived

toxic loves from their

entourage

how do these beings develop

finally in adolescence at the age

adult behavioral disorders and

even psychiatric disorders

I discovered the power of

the unconscious at home but also at home

me

and finally one day I agreed to

to do a hypnosis experiment of

regression under hypnosis nothing to see

really with show hypnosis

therapeutic hypnosis the idea is

really two to be in a state

of modified consciousness that allows us

to go explore our

unconscious I was a little bit

skeptical I said okay ok we’ll see

if if I discover something that I

do not know about me right now

it was a bit like a dream

in which I remained conscious

all along and I did not get the impression

that much happened

extraordinary is several months

after that I realized that

finally it changed my life

before that I was someone very

sociable good I am I am always

sociable but advance to ten years I had

need to fill my schedule

to always be busy

professionally and personally

I did not have much time for

me and after that I surprised myself

on the contrary enjoyed those moments of

face to face with myself at

discover my inner world and

discover this strange beast the

loneliness and that finally took me

very far since I left in

trip alone a few years after

so I could realize another one of my

dreams but most certainly I would have

not realize this trip alone I would have

not the courage to do if I had not

did this session so I left in

india the country par excellence of

introspection of meditation

I continued this work on me and at

as I met a whole

lots of people and without realizing it

in fact I guide them is in turn

in this journey inside

of themselves to discover their

sufferings their limitations try to

release them too and that’s the things

chained themselves very naturally

when i came back in 2012 i got

so installed as a therapist

independent and I realized this

other dream of helping people who are

who are in pain then everything

that to explain to you that all these

experiences indeed have changed me and

today a field of science

tells us about how the environment and

what we saw little imprint in our

cell

it’s called epigenetics

epigenetics what are these

chemical changes that will change

gene expression without there being

of change whose DNA sequence

these people these changes can be

inherited and irritable so cell

in cell during the divisions is

reversible

a simple example you have some

skin cells of the back cells of

nerve cells all these cells

are different

how is it possible from a

same cell from the same

sequence and six sequences does not change

not from the beginning to the end of your life and

yet these cells are different

that’s what it’s based on

epigenetic marks so these

small chemical changes that are going

give each cell type a

different profile

so that’s at the cellular level

now at the level of organisms

whole I’ll give you an example

very simple is that of bees

the bees that initially are all

the same

finally there is one that is going to be

fed with royal jelly she’s going

become twice as big as

others almost and she’s going to be

able to lay so we see that

the environment what are we going to eat in

anyway what the bei is going to eat is going

change its characteristics and its

science skills one studies

often the mouse then in the mouse

we could see that behaviors

different could be linked

with epigenetic profiles

different from mice for example which

are scared and who stays in a cage at

him but that we compare with mice

who they are explorers who are going

go to the street in the cage even though

it is reached and settat and well one

sees when these two types of mice

their behavioral differences can

be related to differences

of epigenetic markers what we

also see is that stress can

influence its epigenetic marks

and behind influencing the behavior

for example

in mice in mice

gestation if the female is in contact

with an evil that is going to be aggressive

stressed savalas and this stress is going to have

a later impact in the little ones a

stress in the very early stages of

life of the little mice is also going

have an impact on their management of the

stress later and will even be able to

induce behavior at home

depressive

it can be a stress like

separation from their mother so

repeated and not expected so he did

not always the same thing so here we go

I have in the mouse we also see

that these epigenetic marks that

are therefore the consequence of what the

mouse is going to live and that are in connection with

behaviors we see that these

marks may be transmitted to the

course of the generations

it makes us ask a lot of

questions in humans how

it’s happening so it’s more complicated

to study the human being but a group

and I take this example because it’s

studies that have been done

here in geneva

this group has studied women

who had experienced violence

sexual or physical in gold in

their childhood and what they discovered

what was one of the natives who has

also involved in the response to

stress that showed an increase

of methylation and so

interesting in black so stopped them

controls and blank we see that it’s

people who have been abused

many times and in between is

all intermediaries

so in fact there is even a

increase in the number of methylation

depending on the severity of the

trauma and abuse and they even

could prove that one of the girls by

example of a raped woman had the

same epigenetic marks as his

mother while she even never had

been raped and the doctoress nothing

giacobino tells us about scars

present in the dna and this

possibility to have a

transmission over generations

then would we be the product in

effect of the traumas we experienced

but also those of our ancestors

you have to understand that all that

it’s valid for all of us

finally since a trauma

what is an event that goes

create an emotional shock and that

can not digest it happens

not to accept

and finally we’ve known since

decades psychologists and

psychoanalysts tells us about the effects

traumas from the experiments on

behaviors today the

biology adds a link that of

epigenetic footprints and what

happens in our cells then in

effect it concerns us all but we

is not always aware of our

emotional reactions

Besides, I want to ask you

little question for you where are you going

emotions is what you can me

say like that to show me for you

or are they happening

emotions at you ok ok I see that

some people show me the head

so that’s what I answered the

first time I was asked

so neuroscientific question that’s it

pass the brain where emotions

limbic neurotransmitter head but

in fact yes it’s also happening in the

intestines I heard and in the body

we can feel this construction in

the heart when we are anxious

no fear in the stomach

so the emotions are happening too

in the body but we often do not have

really used to go listen and

to be in touch with what’s going on

inside of us and the question

what is it like to do

release his emotions today there are

more and more techniques that works

on trauma resolution

very often these techniques they

use hypnosis or regressions

in any case will bring us to revive

the trauma that she is conscious of or

in any case live the emotion fully

feel it and accept and

to welcome everything that happens in

allows us at some point like to

metabolize her physical sensations

today there is even an institute of

research that works on the peaks

states ie the states of

consciousness hyper operate the states

of advanced consciousness that we

brings the very very states

comfortable like for example peace

interior where joy and who we

would bring his statements permanently and

in fact in this model big brands

what does it tell us about how the

awareness and trauma could

understand one’s biological level and

tells us that we would all have access to these

hyper functional states of consciousness

it’s just our trauma and

those of our ancestors that prevents us

to live them

so my question today is when

we do this work when we

free from our emotions

do we erase his scars that

are in the genes

are we waking up somewhere

epigenetic markers that go who

go to those who will arrive when we live

trauma and I really think

that this is where the challenge of the

biology and psychology of the 21st

century and in any case it’s the challenge

that I start for the next

years

so today my message is what

I want to tell you to resume

the phrase in Nietzsche’s sentence

it’s to invite you to become what

you are expressing the most beautiful

part of you because it can

really change things at the level

relationships with your loved ones and

and all the way you will live

everyday

I observe every day people who

change their behavior for you

give a small example of people

who have anxieties for example without

know why in the morning and wake up

there is anguish that is there and in

a few sessions the person is going

totally break free and this

impression of tight chest play and

more where other people and that

may be facing the partners facing

a child who makes comments and

every time the person will feel

be attacked or devalued and

same in a few sessions

the reaction is no longer the same

feeling in the face is no longer the same and

incredibly it changes

the reaction of the famous person in

face she comes more leaning on the

button that was painfully base

so here I want to invite you

to become who you are and the recipe

Is simple

so it was simple but after the

work a little tedious it’s

first of all to become aware of who

you are

what are your trauma what are

your blockages your fears is what you

want to be too, then it’s

to decide decided to change some

thing

and sometimes these two stages when we

made and well it’s not I do not know

enough because we have to find the

tools that allow us to

release

alas once more it’s not I

ask you not to believe me me there the

first I did not believe in all that

but on the other hand to try and for each

of you the tools will certainly

different each must find a small

little way to be able to break free

so here I will end on this

carl gustav jung’s sentence telling us

that all that is not put in

trust comes back in the form of destiny

and I really believe that power is

in us finally and it is in this duty

to do this work

not just for us but it’s

also an act of responsibility

for future generations
