how does the heart work,
尋ねたとすると
すぐに答えられるでしょう
oxygen for carbon dioxide.
答えられるでしょう
it's hard to understand
わかりにくいものです
at a brain and understand what it is.
何をしているかわからないからです
not a pump, not an airbag.
機械的なものではありません
in your hand when it was dead,
you have to go inside a living brain.
生きた脳を観察する必要があります
the brain is electrical and it's chemical.
代わりに電気的、化学的に動作します
100 billion cells, called neurons.
1000億個集まってできています
with each other with electricity.
電気信号を伝えます
in on a conversation between two cells,
こっそりと聞いてみましょう
to something called a spike.
聞いてみるのです
or your brain or your teachers' brains,
記録したりはしません
friend the cockroach.
very similar to ours.
持っているからです
about how their brains work,
少しでも分かれば
about how our brains work.
多くのことを学べます
in some ice water here
Greg Gabe: Yeah ...
(グレッグ)こんな感じで
they become the temperature of the water
体温が氷水の温度に下がります
so they just basically "chillax," right?
おとなしくなるしかありませんよね?
痛みを感じたりしません
about what we're going to do,
実験から学ぶことができます
to understand the brain.
科学的な実験です
has all these beautiful hairs
美しい毛があり
that is going to send information
脳に伝える
it's hard because they can feel you coming
あなたの気配を感じ
they start running.
捕まえることは困難です
this information up to the brain
情報を電気信号にして
with electronic messages in there.
素早く脳に送り込みます
by sticking a pin right in there.
of a cockroach --
this electric message is going by.
信号が流れていきます
let's see if you guys can see this.
目を離さずにいられますか?
that we came up with
スパイカーボックスという
equipment in a research lab,
高価な装置にとって代わるもので
in your own high schools,
自宅の地下室でも実験できます
and turn this on.
sound in the world.
is doing right now.
起きている事なのです
making these raindrop-type noises.
奏でているのです
やってみましょう
スパイク状だと言ったことを思い出して下さい
the axon looks like a spike.
looks like in just a brief second.
That's an action potential.
この部分が活動電位です
in your brain doing this right now,
みなさんの脳で行っていることです
about what you're seeing, hearing.
情報として送ります
about vibrations in the wind.
検出します
and hear if we see a change.
音がどう変化するか聞いてみましょう
if you hear anything.
教えてください
with a little pen here.
触れて見ましょう
in neuroscience to understand this.
長い時間がかかりました
the more spikes there are,
is coming up to your brain.
an experiment with electricity.
実験の1つですが
only taking in electrical impulses,
受け取るだけではありません
something that's electric
I'm going to plug them onto the cockroach.
コックローチの脚に刺します
I'm going to plug in into my iPod.
iPodを接続します
work in your ears?
動作するか知っていますか?
in your phone, or iPod, right?
電池がありますよね?
into these magnets in your earbuds
電流を送り込むと
and allow you to hear things.
that our brain uses,
脳が使うものと同じなのです
送り込むこともできます
when we play music into the cockroach.
何が起こるか見てみましょう
It's moving on the bass.
ベースの音に合わせて動きます
カーステレオを持っていたら
are the biggest speakers.
知っていますね
have the longest waves,
長い波長の音を鳴らしますが
these things to move.
動かすのです
that are causing electricity.
スピーカーだけではありません
another person out on the stage here
上がって来てもらい
happened in the history of mankind.
コックローチの脚のコラボです
think about neuroscience
神経科学のことや
the neuro-revolution.
考えてください
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.
