to access the brain,
as a graduate student
to get access to these tools.
e accedere alle attrezzature.
because one out of five of us,
perché una persona su cinque,
will have a neurological disorder.

and I brought some here tonight,
come quella che ho portato qui stasera
(Applause)
(Applausi)
to record from your brain.
a registrare il tuo cervello.
your arm for science,
per la scienza,
I'm putting electrodes on your arm,
sul tuo braccio,
brain, what am I doing with your arm?
che ho detto di registrare il tuo cervello.
inside your brain right now.
di neuroni nel cervello,
back and forth, and chemical messages.
right here in your motor cortex
nella corteccia motoria,
when you move your arm like this.
se muovi il braccio così.
across your corpus callosum,
to your lower motor neuron

what your brain sounds like?
So go ahead and squeeze your hand.

that's happening here.
and try to see one of them.

happening right now inside of your brain.
but let's get it better.
ancora più interessante.
verso i tuoi muscoli.
down to your muscles right here.
a signal down to your muscles.
un messaggio ai tuoi muscoli.

in collegamento.
and we're going to plug it in
to squeeze your hand again.
ancora la tua mano.
over here so that you get the --
a little bit weird at first,
(Laughter)
and someone else becomes your agent,
e qualcun altro se ne impadronisce,
so go ahead and give it a squeeze.
perciò continua a stringere la mano.
and turn your hand.
MG: Nope.
MG: No.
MG: A little bit.
MG: Un po'.
and it's also controlling his arm,
il tuo e il suo braccio,
(Risate)
if I took over my control of your hand?
se io controllassi la tua mano?
such a good sport.
stati così bravi.
all across the world --

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.
