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 was able to make 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 it 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 that’s where it’s 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
