I do not play a piece improvised age
I’m trying notes it’s not perfect
no matter i’m looking i’m trying i’m trying
[Applause]
it does not matter if it’s perfect
there I work I have a little fun I
I’m looking for
because I am a researcher my
my field of research
it’s assisted surgery by
computer I work with
Surgeons
I am not a surgeon myself
it’s me with a blue cap you have
I like bonnets short my door I
works with surgeons but I
am not a surgeon my domain
it’s my skills that I learned to
school are the mathematics the
physics and computer science
so I’m not a crack in these
areas either but I get to
express myself with then you go to me
ask how can I be director
research at the national institute for
health and medical research and
president of the scientific society
international surgery assisted by
computer me I will explain it to you
it’s simple it’s simple I have a
method mine it’s just mine
first i like to discover
I tried I like to learn
to understand I am patient I try
I try again and again I work
not alone
I work with people with a lot
of networked people I’m going to look for the
skills everywhere I try in
all areas you will see
I try everywhere but everywhere you go
see and I give I give a lot
give a lot I give ideas
I admit idea I give emotions and
then I’m not afraid not afraid not even
not even scary and even if I’m scared
I do it anyway because sometimes
I’m afraid I’m afraid of missing
I’m afraid of ideas I’m afraid of evil
to play but I’m still
so I will introduce you to a small
little bit of that in the minutes that go
follow with some examples follow me
I am in my job as a researcher
faced with problems like this
there I introduce you eric eric it’s a
patient who has dystonia dystonia
is a neurological disease
motor disorders
it’s a little like the disease of
parkinson’s except that dystonia these are
muscle contractions
involuntary
about thirty years ago
a French neurosurgeon invented
a technique called the
deep brain stimulation and who
is to insert into the brain of
patient from very small electrodes to
inside the brain and who will go
electrically stimulate small
structures and stimulating them in
continuously electrically all the time
walk we see eric three years after he has
grown he changed and these troubles
engines have disappeared so éric is not
cured but these motor disorders have
disappeared by stimulation like the
brain is a bit complex
when we stimulate at one place we stimulate
a little bit everywhere around like the
neurosurgeons and neurologists
do not completely agree on
the place does not have an exact consensus
on where to stimulate and what
probably it is necessary to stimulate zones
different for each patient there are
in some patients
negative side of the troops of
the emotion of apathy and sometimes even
the appearance of addiction as
gambling addiction people had not
of addiction before and then with the
acquire stimulation acquires one
addiction
that’s where I get in there is where
as a researcher starts my
job
so how do I do I go first
go get my basic skills
in computer science physics
and then the skills of my colleagues
and super super researcher
super student and super researchers
students who work with me and
who have parentheses very often
skills that are superior to
mine no matter I ‘m going to look
their skills we work together
and then we try for example
develops methods that from
medical images of the patient allow
to build a 3d virtual brain of
every patient on whom the
neurosurgeon with reindeer who celebrates his
operations can prepare its insertion
of electrodes could try to be the
more secure and possible to try
to predict it’s side effects
negatives that can happen at
some patients well we’ll go
collect all data from
patients before stimulation after the
stimulation and we will study them these
data to try to see the cases that
walked and cases that did not work
then we use methods like
artificial intelligence for example
which allows us to predict this for
some patients the fact that the
procedure will not work very well or
more must be careful because there
there is a side effect that risk
to appear and the neurosurgeon
tell us
it works it works the durations of
intervention are shorter
the side effects are on the
patients are reduced and there is almost
more infections
so here I’m happy I do not know
always like that but here I am
really happy it’s a research that
ends then we go a little bit more
far this neurosurgeon we would like
know how exactly she operates
how she how she how
surgical instrument she uses
how long with which sequence
then we look for methods that by
observation we will observe them in the room
op we will watch what she does and
then by observation
we will analyze its practice and goes
extract graphs from models that
expresses his profession
these models can serve us by
example if we apply them on
operating room nurses we ‘re going
she also observed these patterns can
to use to build
virtual reality environments
that allow its theater nurses
operative to train continues the
continuous progress of
research
today we start Thursday the
lab starts with me a project
of research
so you do not talk about it too much because
I have not published yet on it and
so it stays between us it’s a project
of research where we are going we finally
studied the brain activity of
surgeon while he is operating then not
while it operates because it’s okay
a little disturbed we will start during
that he trains and we will measure
the electrical activity of his brain
while you work with as
goal behind trying to identify
the progression curve of the surgeons
how does he react to stress how he
responds to an unexpected event and
think that have little impact like that the
progression and learning the
surgeon and after you will tell me
after stone you going to do after there
in five years in ten years
where will you find yourself what is
is going to be ideas so how to expand
this field of creativity
how to find how to open
doors there too I have my method very
simple I search everywhere then everywhere
I search everywhere I try everywhere
everywhere it means first to
abroad I travel I travel a lot
i go to the united states in canada in
norway in germany or japan
I work with makoto who is a
Japanese surgeon and we study
together the differences in practice
between the operating room nurses
French and block nurses
Japanese operative and I look if
the methods that I develop at reindeer
can be used in Japan to
united states in canada
I try everywhere then when I tell you
by everyone everywhere
it’s also in all areas I
work with you’ve seen
mathematician and computer scientist physicist
urologist surgeon but also with a
professor of business management
with a design teacher the school of
fine art of strasbourg
and then I tried with actors
with a rock guitarist with
visual artists with an example the
plastic artists three years ago I
met fred and flavian who are two
plastic artists who make installations
digital
I wanted to understand how
do it to work what is their
creative approach and I wanted
use this creative approach to
improve you’ve seen this
3d representation of the brain there and this
representation is a little complex and I
wanted to make sure that their method
simplifies it and allows
send more information to
surgeon
so we’ve seen each other twice
three times four times we were full
of meetings
I presented what I do they have me
presented what he was doing
we
discusses enormously enormously
could not do anything it can work then
not at all not good it happens
it’s research
we try sometimes it does not work
other examples
about a month ago a month and a half ago
neurosurgeon with whom I work
who also deals with the surgery of
epilepsy so surgery
epilepsy it’s a bit peculiar
it’s in the context of patients
severe epileptics for a lot of
epileptic seizures a day is the only
solution when medications only work
the more it is to go to surgery
the small brain area that initially
epileptic seizures the
neurosurgeon to day arrives in my
office
hello stone I had an idea
I would like to hear the crisis
of epilepsy I would love to hear
to see where and start to me you me
talk about hearing as I think
music two three players before I had
met jesse narrative it’s a musician
who makes electronic music and
i said jessie give you the signals
recorded on patients
epileptics and turns emotion into
music
alas what do you hear these the
first results sent to me
just jesse tuesday
I ‘m trying I’m trying I’m looking I’m trying
cheat I succeed it’s search here
even there with you right now there on the
scene
I ‘m also looking for I’m in my
researchers approach I give I
communicated
I give the few times it’s me
happened to be on a stage like lala
in concert I felt that we must give
we must give everything we receive
receives no matter what it takes
it’s the base it’s the condition
needed so here too I give you
I have fun too you saw and I
work and then I will learn I
will discover as you meet me
you too today you learn
discover meet you too
in an approach of researchers
today the like me you are
researchers for a better life
ours and then that of others
question is you what is your
method
[Applause]
