00:00You are able to hear a sound and perceive almost instantaneously a color specific?
00:06You could be part of a particular group of people, about 4% of the world population,
00:12capable of proving the synesthesia.
00:14It's not you who imagine things.
00:17A new study shows that the synesthesia is quite real,
00:20and the scans of the brain in attest.
00:22When these people synesthesia hear the colors,
00:26the scans reveal that the parts of their brain liées to the view and sound communicate between them.
00:32Given that the synesthesia seems to be genetic,
00:35some researchers chose three families,
00:39where this characteristic was present.
00:41They have then played with the sequencing of the DNA
00:43and compared the genes of the synesthesia of the same family
00:47to those who had been given.
00:49They still haven't completely confirmed this unique characteristic.
00:52But they have been able to restrain a few 37 genes possible.
00:58Sometimes, after a seat in a uncomfortable position,
01:01you may have maybe felt bumps or an engulfing in your arms or your legs.
01:06You could think that this had to do with a bad circulation sanguine.
01:10But in fact, this could be due to a small thing called the paresthesi.
01:15It's when your body begins to feel the sensations of the habit of the body
01:19because your nerves are compromised or irritated.
01:22The paresthesi can give you anything.
01:24It's a sensation of burning to this sensation of a gênant
01:27that your arms or your legs will not respond at all.
01:30It could even add some demonstrations
01:32or some good old fourmillements.
01:35Normally, this would not take you more than 30 minutes.
01:43If you have repeated episodes of paresthesi
01:48without reasons apparent,
01:49it's preferable to consult a specialist
01:52to ensure that everything goes well.
01:54You know what also means to be verified?
01:57If you have already given a thumbs up to this video
01:59and if you are subscribed to the channel.
02:02You know, just for sure to be sure of nothing to miss.
02:07In normal time, you never think of your stomach
02:10or all the chemis that it contains.
02:12Can you imagine if a day this substance disappeared?
02:16It contains an acid chlorophyll
02:18which is also used in the engulfing,
02:21the water, the caoutchouc
02:22and the acier.
02:23If ever you inhale it,
02:25you will have serious problems of respiration
02:27and in your nez.
02:29Every time you mâche something,
02:31your stomach begins to produce
02:32its gastric acid.
02:34They are useful because they can
02:35decompose the proteins,
02:37activate the pepsine,
02:38eliminate all the bacteria
02:40that you have been able to avate
02:41without even knowing.
02:42And signify your nourishment
02:43to go,
02:45well,
02:46towards the sortie.
02:47Without this acid,
02:48the food would remain right there,
02:51turning into a field of reproduction
02:53for the bacteria.
02:55The proteins and the nutrients
02:56would not be absorbed.
02:58Your breakfast could quickly
02:59pass through your digestive system
03:02and you would end up
03:03by expulsing the non-digestion
03:05of the non-digestion food.
03:07There is a reason
03:09for which the paper coupures
03:10make so bad.
03:11For the beginning,
03:12they produce
03:13on the ends of your fingers,
03:14which are very sensitive areas.
03:17It is because they are
03:18full of receptors
03:19which are like the receptionist
03:21of your body,
03:22you aidant to determine
03:23the size,
03:24the shape,
03:25the texture
03:26and the temperature
03:27of the things that you touch.
03:29When you cut with the paper,
03:31these receptors
03:32are immediately solicited,
03:34envoying
03:35information
03:35to the brain.
03:36The paper coupures
03:38don't look like
03:39a cutting net
03:40made by a knife
03:41by a needle
03:41in reason
03:43of the edge
03:43of the leaves.
03:45It expose
03:46even more your receptors.
03:48The paper coupures
03:49don't hurt
03:50and don't coagulate
03:51not well,
03:52which allows
03:53the nerves to live
03:54and even more
03:55comfort.
03:57We always use our hands,
03:59so these coupures
04:00continue
04:00to be opened
04:01taking an infinite
04:03to heal.
04:04The paper is often
04:05treated
04:06with chemical products
04:07which can irritate
04:08your skin
04:09from the surface.
04:10The déjà-vu
04:11seems to hit
04:12the null part.
04:13You are not a sorcerer
04:14and you don't communicate
04:15with the spirits
04:17of the au-delà.
04:18It is simply
04:19your brain
04:20who works well.
04:22According to the doctors,
04:23the déjà-vu
04:24happens when two parts
04:25of the brain
04:25have a little bit
04:26to understand.
04:27These two parts
04:28are located
04:29on each side
04:29of your brain
04:30just above
04:31the top.
04:32They are
04:33a bit like
04:34the memory
04:34of your brain
04:36and help you
04:37to remember
04:37certain things
04:38like the place
04:39or the face
04:40of other people.
04:41They even
04:42even the emotions
04:43and are in charge
04:44of the language.
04:46Now,
04:47in each zone
04:48of the brain
04:49called the lobes
04:50temporals,
04:50there is a region
04:51called the hippocampes.
04:53It is responsible
04:54of the memory
04:55at short term.
04:56Sometimes,
04:57the brain
04:57can encounter
04:58the little
04:59dysfunction
05:00confonding
05:00the hippocampes.
05:02It is then
05:03that we feel
05:03the already-vu.
05:04All this process
05:06perturbe
05:06your memory
05:07of recognition,
05:08giving you this strange
05:09strange feeling
05:10that you have already
05:11been there before,
05:13or that you have already
05:14met a person
05:15that you have seen
05:15for the very first time.
05:17It is a very normal process
05:19and you are
05:20more susceptible
05:21to prove
05:21the already-vu
05:22if you have
05:22between 15 and 25 years.
05:24It seems
05:25that people
05:26who travel
05:27a lot
05:28or have
05:28the ability
05:29to remember
05:30their dreams
05:31will feel
05:31more often.
05:33It is difficult
05:35to imagine
05:35that a whole civilization
05:37could survive
05:38without anyone
05:39able to see.
05:40This seems
05:42quite improbable
05:43and here is why.
05:45First,
05:46imagine
05:46trying to cultivate
05:47the harvest
05:48without even seeing
05:49what you do.
05:51The preparation
05:52of the soil
05:52would become a nightmare
05:53because,
05:54without the sight,
05:55we would lose
05:56the first
05:56field of the bled
05:57without any reference point.
05:59To collect
06:00a little of this food
06:02would not be
06:03a little of it.
06:03The animals
06:04could be hidden
06:05everywhere
06:06near us.
06:08The communication
06:09would also be complicated
06:10because we would not
06:11be able to read
06:12something without touching it.
06:15Even
06:15our social life
06:16would be different.
06:17Without eyes,
06:19we would have
06:19to be able to see
06:20how to see
06:22without knowing
06:22who he listens.
06:26If you have already
06:27eaten
06:27very spicy,
06:28you know
06:29that it is not technically
06:30hot in terms
06:31of temperature.
06:33So,
06:33why do we feel
06:34that it is burning
06:35even if it is
06:36just coming out
06:37from the refrigerator?
06:38Well,
06:40the spicy foods
06:40contain
06:41chemical components
06:42which are
06:43our body
06:43to alter
06:44its internal thermostat
06:45interne.
06:46First,
06:47our lips
06:48and our tongue
06:49have the feeling
06:50of fire.
06:51Then,
06:52our neck
06:52begins to
06:53couler
06:53and we can even
06:54give a
06:55or two tears.
06:58And suddenly,
06:59our body
07:01augmente.
07:02To
07:02refroidir
07:03things,
07:03we start to
07:05transpirer.
07:06Our lungs
07:07can also
07:07also
07:07signal
07:08and
07:08signal
07:09to
07:09our
07:09diaphragm
07:10of
07:10produce
07:10in the
07:12most
07:12most
07:12of the
07:13most
07:13most
07:14of
07:15the
07:15most
07:15of
07:15the
07:15most
07:15most
07:15of
07:37of
07:37the
07:38most
07:38the
07:39most
07:40of
07:40the
07:40the
07:41the
07:42are
07:46more
07:48more
07:51than
08:06the
08:08what we call the paralysis of sleep.
08:10The big mystery was to know how the muscles enter into this state of paralysis.
08:15At first, researchers thought that glycine, a neurotransmitter, was responsible.
08:21The research showed that even if we blocked the glycine production,
08:25the muscles remained fixed.
08:28It took a little more time to discover that to maintain these immobiles,
08:34it takes both of the glycine and another chemical substance of communication, called GABA.
08:41We are not as well as our ancestors, but we always have the chair of a poule when we have
08:46cold.
08:47It's because of these small muscles in our follicles pileux,
08:50called muscles erectors of the skin, who tire these last ones to the top.
08:55For the animals to furrow, this characteristic helps to stay at hot,
08:59but for us, it does not accomplish anything in terms of heat.
09:03However, we, and some other creatures less poilus, have preserved this capacity over the years.
09:10These experiences have been carried out to know more about this chair of poule.
09:14We found three key factors.
09:16These muscles erectors of the poils, the lymphoma, the lymphoma and the follicles pileux.
09:21When we tried to influence on the lymphoma, the growth of the poils has slowed down.
09:26These lymphoma and the follicles pileux work together, creating a chemical synapses.
09:31Ainsi, the chair of poule is not only a quick solution for a low temperature.
09:37They could also communicate to our cells cells to make more of the poils at long term.
09:43That's why the loss of these muscle muscles could be liable to the pelvis.
09:48Carvic dish.
09:49Thanks.
09:49Thanks for having me
