ser fascinada pelo cérebro,
are fascinated by the brain,
do funcionamento do cérebro.
about how the brain works
neuroscience in schools.
why is that the equipment
universities and large institutions.
em grandes universidades e institutos.
to access the brain,
as a graduate student
to get access to these tools.
e ter acesso a essas ferramentas.
because one out of five of us,
will have a neurological disorder.
vai desenvolver um problema neurológico.
for these diseases.
what we should be doing
in the eduction process
so that in the future,
para que no futuro
becoming a brain scientist.
em se tornar um neurocientista.
de laboratório Tim Marzullo e eu,
my lab mate Tim Marzullo and myself,
this complex equipment that we have
enough and affordable enough
or a high school student,
ou estudante de ensino médio,
in the discovery of neuroscience.
da descoberta da neurociência.
uma empresa chamada Backyard Brains,
a company called Backyard Brains
and I brought some here tonight,
do tipo "faça-você-mesmo"
de fazer umas demonstrações.
Então vou precisar de um voluntário.
(Aplausos)
(Applause)
to record from your brain.
vou gravar a partir do seu cérebro.
SK: Não.
seu braço pela ciência,
your arm for science,
I'm putting electrodes on your arm,
e você deve estar imaginando
se eu disse que ia gravar seu cérebro.
brain, what am I doing with your arm?
de neurônios dentro do seu cérebro agora.
inside your brain right now.
back and forth, and chemical messages.
impulsos elétricos e químicos.
right here in your motor cortex
bem aqui no córtex motor,
when you move your arm like this.
quando mover seu braço assim.
across your corpus callosum,
pela sua medula espinhal
to your lower motor neuron
chegando aos seus músculos aqui,
por estes eletrodos aqui
is going to be picked up
exatamente o que seu cérebro vai fazer.
is going to be doing.
SK: Não.
what your brain sounds like?
Vá em frente e aperte sua mão.
So go ahead and squeeze your hand.
happening right here.
that are happening
motoras que são acionadas
até o músculo, e enquanto isso,
out to her muscle right here,
que acontece aqui.
that's happening here.
o que está acontecendo.
and try to see one of them.
que está acontecendo no seu cérebro.
happening right now inside of your brain.
but let's get it better.
mas fica ainda melhor.
GG: Miguel, certo.
down to your muscles right here.
os seus músculos aqui embaixo.
a signal down to your muscles.
para os seus músculos.
a nerve that's right here
que fica bem aqui
these three fingers,
esses três dedos,
that we might be able
que podemos estimulá-lo
do cérebro que percorrem até sua mão
going out to your hand
when your brain tells your hand to move.
quando o seu cérebro der o comando.
your free will
isso tira você do controle
any control over this hand.
que provavelmente é bem aqui.
quando subiu aqui.
and we're going to plug it in
to squeeze your hand again.
quero que feche sua mão de novo.
over here so that you get the --
para que você consiga...
a little bit weird at first,
(Laughter)
and someone else becomes your agent,
e alguém comanda por você,
Então, aperte bem a mão.
so go ahead and give it a squeeze.
pode continuar e apertar a mão.
and turn your hand.
MG: Não.
MG: Nope.
MG: A little bit.
MG: Um pouco
seu braço e o braço dele, também.
and it's also controlling his arm,
if I took over my control of your hand?
se eu passar a controlar a sua mão?
such a good sport.
tão participativos.
ao redor do mundo...
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.
