[Music]

[Applause]

the body at least has always made us

this is the man of cro magnon

until today going through

all ancient civilizations

the first treatise of our life we

comes from the Egyptians who a thousand five hundred

years before BC had already

identified many points

neuralgic of the body including a

incredible brain description

all that was described in a document on

famous warlock papyrus fight a

American collector who had

did the question and he did

analyze and galleries you also need

to speak Greek

Hippocrates, whose treaties and

anne written 400 years before

jesus christ he no serious backhand is

considered the father of medicine

modern then that he is the first to

propose treatments for

problems related to gangs afterwards

vitruvian 1 pm Roman theater was him

also interested in as he was

fascinated by the operation infinitely

complex of like the famous drawing of

leonardo domenici the vitruvian man puts

in pictures the proportions rejects lynch

human body as measured by glassy

exercise is now the one

exciting and all this fascination

for the human body still continues

today hang himself in his more

simple expression

the man at the end sapiens

is a super assembly of trillions of

billion molecules predominantly

water molecules of course but also

mineral fats and carbohydrates

protein amino acid hormones

obviously the dr and many others

again

this is called the molecules of

leiris with millions of years

of evolution of atoms associated

between them to form these molecules of

life afterwards the molecules get

are associated with each other to form

the first cells live the

broken cells agnès them but they

had the opportunity to breed

and evolve with the evolution of

molecules have joined together for

form a lot more cells

specialist and its specialized units

have joined together to form

living things much more complex

until often hands of conquest and

molecular the humans the human is

so a super assembly of sorting of

billion molecules now 100

in a precise hierarchy by

triads 2 billion interests that this

but even better the human body finally

test chemical reactors and at all

moment of our lives millions

sometimes billions of reactions

chemicals occur in the car and its

chemical reactions menus allow to

digest the food to provide us

the energy needed to move us

to defend ourselves against invaders

to pinch short of living and survival

thanks but better still this fabulous

chemical reactor is still at the

balanced

nothing is lost nothing is created everything is

transformed

audi a3 of the neighbor 1789

the human body is in balance but a

very fragile balance

a balance that is disturbed by everything

that we do everything we see everything

what we take out all that we

feels eating 10 may 13 fps and drinks from

Alcohol gives a hammer on

pushes watching a horror movie

his whole voice altered the kilims

chemical in our body is in response

at stimuli our cellar produced a

myriam chemical substances that are going

allow us to deal with these

events

molecules are able to

neutralize the acidity of the guards and

the alcohol

decrease the pain of all destroyed

the adrenaline

in other words to adapt ourselves

humans at all these sweat

and to illustrate this concept what’s

better than love indeed you have

you already asked the question why you

had butterflies in the stomachs of

heats an extension a fair control

at the sight of someone who attracted you

why felt a sense of

happiness and comfort in seeing

someone who was very dear to me and what

even after so many years is that soul

or impotence stimulus that will alter

the chemical kilims of our case and

thanks to the imaging applications the

his is being rated able to study

body chemistry but in love and they

have identified the chemicals

officials

the passionate love of loving desire to

the pain of love etc

love is chemical such practices

love at first sight you know the shot of

lightning the case of people will be happy

that the quarter starts to beat is serious

and that sea packets that we do

things for quite consistent

since I had to coast-hot think

it only happens in movies

to deceive the thunderbolt exists

really it causes a moody’s but some

very weird behavior sometimes

almost elastic

scientists have been looking at this

subject and will not be surprised

to learn that what they found

it’s all about the brain

when you see your love at first sight

in your brain you have a

chemical activity of the residences of

accursed culture or m6 then go away

be translated and that simon take the

total control of your body good wagon

hooked practice and

science makes that useless brain of

people they felt a love

passional a term less romanticized but

more scientific to say blow of

lightning

did they find fascinating the

love at first sight to find one’s way

very small area of ​​a brain in

full heart of this one so we call

the caudate core and everything is controlled by

four

this chemical because small

substances with very large effects

sound

the first is the infinity of the mine

a real drug the dignity the mine

is one in natural vitamins and

when it is produced in our

brain it provides a sense of

comfort and well-being

he is hardly he is alone in the world

the head

been shot and the phrase devoted on

is on a cloud

this is the bulk of this drug

natural there end the year

adrenaline by dopamine she she

will give us an extension study

because in our brain we have

billion bep accounting what we

calls during it the current goes to

through the neuron through

neurotransmitters especially

the knuckled mines

when we see our love at first sight

is going to have tons of six months we’re going

see time to doubt but released

in our brains these are going

literally short circuit our

neural network and neutral our system

nervous or even beautifies

consequences of this 100 m it was the

first is that it stimulates the mood

and the enthusiasm we touch joyfully

happy we are always on

do not know why but we’re all

time because we are under the drums and

the effect of dopamine is

unfortunately some people have

an excess of dopamine

so that does not put me in a

state of excitement I’m sure

you know what I ‘m saying especially for

you but if you know about a thousand

time surely some who is it

come

the next very interesting you know

that my characteristic behavior of

people that took a stroke of age madness

he is very weird

you know the expression it’s I do not know

not what took me I was not in

my normal state and well locate this

substance called the

norepinephrine norepinephrine is

a molecule that causes a feeling

the bottom

it will interfere with our processes

decision making she’s going to do that one is

less rational and sometimes

irrational and she will make us

do all kinds of things that we do not

would not do in a normal state

these lifts of norepinephrine and the

last you know her well

adrenaline the molecule of urgency

adrenaline has several effects

biological young authors she us

makes it more alert it raises

our body temperature

but above all it increases the

heartbeat

which makes the heart beat faster

better a very organic farm name

when we talk a lot less about

adrenaline is that it allows

to increase the blood pressure

what he means to be beautiful

like a tomato and here

we have all the scout elements

crowd one is red like a tomato the

heart of the debate

we have heat we are laughing all the

time no reason we do things

irrational

love at first sight it’s chemical we do not

can not prevent a shot but we

has gunshots rehearsals in

our life we have nudges to

any age we were shot

lightning in any

circumstance

but so beautiful so intense is the blow of

lightning

all helps a science of the

confirms love at first sight

it does not last

indeed to the famous what is progressing

in a romantic relationship

the concentration of the moles one of the

love at first sight this morning decrease to

from 18 months to disappear

completely

after a few years but do not have

fear because chemistry comes to the rescue

lovers and passionate love can

to turn into a love that wants

called sustainable but who can

resist all life and only one

molecule is responsible for this phenomenon

unbelievable

this is the site to the movie the yen script to

me with the molecules of the thunderbolt

the parking of a hormone is called

their name of attachment she’s going

take over from the hit molecules

from lightning to a puzzle at the games

and a muscle relaxant

so when two thunderbolts that

are no longer in love

meet in the agreement the staff must

be produced and relax their muses

have decreased their tensions and caused

the feeling of comfort and well-being

durable

searched for many years and

that’s what will transform love

passionate in an oral love the blow of

lightning is chemical but it does not want

not but the system takes over for

a love of life love is that

there you are impotent stimulus that

will alter the chemical equilibrium of

our body these are huge amounts

scientific research points that

have allowed this understanding of a

ultimately ubiquitous in the

life

a superb illustration of the importance

scientific research

fundamental to understanding the

human physiology because only including

a horn sound but at the molecular level

will allow us to develop

more effective therapies to treat

the evils that plague us zooms

and especially those who touch the

brain or a there are processes

we still do not escape

our understanding and with

trillions of billions of molecules

maintained a meaning in one and that it is

perfect by trillions of billions

of interaction one can say without fear

that homo sapiens man is a weak

the chemical reactor always filled with

a lot a lot of secrets

thank you

[Applause]
