a company called Backyard Brains

and I brought some here tonight,
neurociencia y que traje aquí esta noche,
alguna demostración.
(Aplausos)
(Applause)
to record from your brain.
grabaré tu cerebro.
el brazo para la ciencia,
your arm for science,
I'm putting electrodes on your arm,
electrodos en el brazo,
brain, what am I doing with your arm?
¿qué estoy haciendo con tu brazo?
inside your brain right now.
unas 80 000 millones
back and forth, and chemical messages.
y químicos de un lado a otro,
right here in your motor cortex
de la corteza motora
when you move your arm like this.
el cuerpo al mover el brazo así.
across your corpus callosum,
to your lower motor neuron

what your brain sounds like?
el sonido de tu cerebro?
Así que adelante y aprieta la mano.
So go ahead and squeeze your hand.

motoras puestas en marcha

out to her muscle right here,
that's happening here.

tratar de ver a alguno de ellos.
and try to see one of them.

happening right now inside of your brain.

but let's get it better.
pero vamos a mejorarlo.
un impulso a tus músculos de aquí.
down to your muscles right here.
a signal down to your muscles.
un impulso a los músculos.
a nerve that's right here
these three fingers,
hasta estos 3 dedos,
that we might be able

going out to your hand
que se dirigen a tu mano
when your brain tells your hand to move.
su cerebro le diga que se mueva.
ella te quitará tu libre albedrío
your free will
any control over this hand.
sobre tu propia mano.
cuando subiste al escenario.
y vamos a conectarte
and we're going to plug it in
to squeeze your hand again.
aprietes la mano de nuevo.
over here so that you get the --
aquí para que te llegue...
a little bit weird at first,
(Laughter)
pierdes tu libre albedrío,
and someone else becomes your agent,
de otra persona
so go ahead and give it a squeeze.
así que adelante, un apretón.
and turn your hand.
así que adelante, aprieta la mano.
MG: Nope.
MG: No.
MG: Un poco.
MG: A little bit.
and it's also controlling his arm,
y también controla el suyo,
hazlo una vez más.
(Risas)
if I took over my control of your hand?
cargo del control de tu mano?
such a good sport.
all across the world --
the neuro-revolution.

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.
