how does the heart work,
comment le cœur fonctionne,
Il pompe le sang.
vos poumons,
du dioxyde de carbone. C'est facile.
oxygen for carbon dioxide.
le cerveau fonctionne, c'est difficile à comprendre
it's hard to understand
un cerveau et comprendre ce que c'est.
at a brain and understand what it is.
ni un coussin d'air.
not a pump, not an airbag.
c'est juste un morceau de graisse.
in your hand when it was dead,
you have to go inside a living brain.
Parce que le cerveau n'est pas mécanique,
the brain is electrical and it's chemical.
100 billion cells, called neurons.
Ces neurones communiquent entre eux grâce à l'électricité.
with each other with electricity.
in on a conversation between two cells,
to something called a spike.
or your brain or your teachers' brains,
friend the cockroach.
very similar to ours.
sur le fonctionnement de leur cerveau,
about how their brains work,
sur le fonctionnement du nôtre.
about how our brains work.
in some ice water here
Greg Gabe: Yeah ...
c'est qu'ils sont anesthésiés,
they become the temperature of the water
la température de l'eau
so they just basically "chillax," right?
donc en gros ils sont cools et relax.
about what we're going to do,
sur ce que nous allons faire.
pour comprendre le cerveau.
to understand the brain.
has all these beautiful hairs
that is going to send information
va envoyer des informations
Attraper un cafard, c'est difficile
it's hard because they can feel you coming
il commencent à courir avant que vous ne soyez là.
they start running.
au cerveau
this information up to the brain
with electronic messages in there.
by sticking a pin right in there.
of a cockroach --
et ce message électrique circule..
this electric message is going by.
j'espère que pouvez le voir.
let's see if you guys can see this.
dans cette invention que nous avons faite
that we came up with
dans un laboratoire de recherche
equipment in a research lab,
dans vos collèges,
in your own high schools,
and turn this on.
sound in the world.
is doing right now.
qui ressemblent à des gouttes de pluie.
making these raindrop-type noises.
que ça ressemble à un pic.
the axon looks like a spike.
looks like in just a brief second.
That's an action potential.
in your brain doing this right now,
qui font ça en ce moment,
sur ce que vous percevez.
about what you're seeing, hearing.
about vibrations in the wind.
and hear if we see a change.
entendre si nous voyons un changement.
si vous entendez quelque chose.
if you hear anything.
with a little pen here.
fallu un certain temps
in neuroscience to understand this.
On appelle ça le codage de débit,
plus il y a de pointes,
the more spikes there are,
Voilà comment vous percevez les choses.
is coming up to your brain.
an experiment with electricity.
non seulement des impulsions électriques,
only taking in electrical impulses,
vous bougez vos muscles.
d'électrique
something that's electric
I'm going to plug them onto the cockroach.
sur le cafard.
I'm going to plug in into my iPod.
vos écouteurs fonctionnent dans vos oreilles ?
work in your ears?
in your phone, or iPod, right?
votre iPod.
into these magnets in your earbuds
vous permettent d'entendre des choses.
and allow you to hear things.
that our brain uses,
ce que notre cerveau utilise,
à nos pattes de cafard et si ça fonctionne,
quand on joue la musique dans le cafard.
when we play music into the cockroach.
Ça se bouge avec la basse.
It's moving on the bass.

et donc ils ont le plus de courant,

Why you should listen
As half of Backyard Brains, neuroscientist and engineer Greg Gage builds the SpikerBox -- a small rig that helps kids understand the electrical impulses that control the nervous system. He's passionate about helping students understand (viscerally) how our brains and our neurons work, because, as he said onstage at TED2012, we still know very little about how the brain works -- and we need to start inspiring kids early to want to know more.
Before becoming a neuroscientist, Gage worked as an electrical engineer making touchscreens. As he told the Huffington Post: "Scientific equipment in general is pretty expensive, but it's silly because before [getting my PhD in neuroscience] I was an electrical engineer, and you could see that you could make it yourself. So we started as a way to have fun, to show off to our colleagues, but we were also going into classrooms around that time and we thought, wouldn't it be cool if you could bring these gadgets with us so the stuff we were doing in advanced Ph.D. programs in neuroscience, you could also do in fifth grade?" His latest pieces of gear: the Roboroach, a cockroach fitted with an electric backpack that makes it turn on command, and BYB SmartScope, a smartphone-powered microscope.
