it's hard to understand
то разобраться сложно,
at a brain and understand what it is.
и понять, что это.
not a pump, not an airbag.
не воздушная подушка.
in your hand when it was dead,
you have to go inside a living brain.
нужно изучить активный мозг.
the brain is electrical and it's chemical.
и химические процессы.

между двумя клетками.
to something called a spike.
под названием «спайк». [Англ. — шип]

friend the cockroach.
very similar to ours.
about how their brains work,
about how our brains work.
in some ice water here
Greg Gabe: Yeah ...
Грэг Гейдж: Ага.
they become the temperature of the water
поэтому их температура снижается,
so they just basically "chillax," right?
и им остаётся только «прохлаждаться».
about what we're going to do,
что мы собираемся делать.
to understand the brain.
чтобы понять мозг.

that is going to send information

it's hard because they can feel you coming
потому что он чувствует ваше приближение
they start running.
this information up to the brain
with electronic messages in there.

this electric message is going by.
let's see if you guys can see this.
Не знаю, хорошо ли вам видно.

equipment in a research lab,
оборудование лабораторий,

the axon looks like a spike.
что аксон похож на шип.
looks like in just a brief second.
в долю секунды.
That's an action potential.
in your brain doing this right now,
делают сейчас то же самое,
about what you're seeing, hearing.
что вы видите и слышите.
about vibrations in the wind.
and hear if we see a change.
есть ли изменения.
if you hear anything.
with a little pen here.

the more spikes there are,
тем больше спайков,
is coming up to your brain.
an experiment with electricity.

something that's electric
если подключить что-то электрическое
I'm going to plug them onto the cockroach.
I'm going to plug in into my iPod.
work in your ears?
наушники в ваших ушах?
in your phone, or iPod, right?
into these magnets in your earbuds
на магниты в наушниках,
and allow you to hear things.

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.
