are fascinated by the brain,
ce proprietăți are și cum funcționează
about how the brain works
nu se învață neuroștiința.
neuroscience in schools.
why is that the equipment
care e foarte complex și scump,
importante și instituțiile mari.
universities and large institutions.
to access the brain,
trebuie să-ți dedici viața:
as a graduate student
și a avea acces la aparate.
to get access to these tools.
because one out of five of us,
will have a neurological disorder.
va avea o boală neurologică.
pentru aceste boli.
for these diseases.
what we should be doing
mai devreme în procesul educațional,
in the eduction process
so that in the future,
pentru ca, în viitor,
de a deveni cercetători ai creierului.
becoming a brain scientist.
my lab mate Tim Marzullo and myself,
și colegul meu de laborator, Tim Marzullo,
complex cu care studiem creierul
this complex equipment that we have
enough and affordable enough
or a high school student,
fie el amator sau elev de liceu,
in the discovery of neuroscience.
la progresul neuroștiinței.
am înființat compania Backyard Brains
a company called Backyard Brains
pentru neuroștiință.
and I brought some here tonight,
ca să fac niște demonstrații.
(Applause)
Sam Kelly: Sam.
to record from your brain.
îți voi înregistra activitatea creierul.
în numele științei
your arm for science,
I'm putting electrodes on your arm,
dacă am zis că voi înregistra creierul.
brain, what am I doing with your arm?
de neuroni în creier,
inside your brain right now.
back and forth, and chemical messages.
și mesaje chimice.
right here in your motor cortex
when you move your arm like this.
când îți miști brațul așa.
across your corpus callosum,
to your lower motor neuron
până la acești mușchi.

SK: Nu.
what your brain sounds like?
Hai, strânge pumnul.
So go ahead and squeeze your hand.
e activitatea motorie de aici.
happening right here.
(Huruit)
ce se propagă
that are happening
până la acest mușchi.
out to her muscle right here,
se poate vedea activitatea electrică.
that's happening here.
și să încercăm să vedem.
and try to see one of them.
de acțiune din creier.
happening right now inside of your brain.
but let's get it better.
GG: Bine Miguel.
creierul trimite la mușchi un semnal.
down to your muscles right here.
a signal down to your muscles.
a nerve that's right here
și inervează aceste trei degete.
these three fingers,
astfel încât să-l putem stimula.
that we might be able
cerebrale de la mâna ei
going out to your hand
when your brain tells your hand to move.
după cum își va mișca ea mâna.
your free will
asupra mâinii tale.
any control over this hand.
Bine...
(Râsete)
care e probabil undeva pe aici.
and we're going to plug it in
această interfață om-la-om.
to squeeze your hand again.
Perfect.
over here so that you get the --
a little bit weird at first,
te simți ca și cum...
(Laughter)
și altcineva acționează prin tine
and someone else becomes your agent,
Nu l-am pornit încă.
so go ahead and give it a squeeze.
and turn your hand.
Începe! Strânge pumnul.
MG: Nu.
MG: Nope.
MG: A little bit.
GG: Un pic? (Râsete)
Încă o dată!
(Râsete)
atât brațul tău, cât și brațul lui.
and it's also controlling his arm,
(Râsete)
controlul asupra mâinii tale?
if I took over my control of your hand?
De ce?
Strânge iar.
atât de cooperanți.
such a good sport.
electrofiziologie!
all across the world --
the neuro-revolution.
ABOUT THE SPEAKER

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.
