how does the heart work,
wie das Herz funktioniert,
Es ist eine Pumpe. Es pumpt Blut.
gegen Sauerstoff ein. Einfach!
oxygen for carbon dioxide.
wäre das schon schwieriger,
it's hard to understand
auf einen Blick durchschauen.
at a brain and understand what it is.
keine Pumpe oder ein Airbag.
not a pump, not an airbag.
wäre es einfach ein Klumpen Fett.
in your hand when it was dead,
wie das Gehirn funktioniert,
you have to go inside a living brain.
schauen, da es nicht mechanisch ist,
the brain is electrical and it's chemical.
100 billion cells, called neurons.
100 Milliarden Zellen,
kommunizieren sie über Elektrizität.
with each other with electricity.
zwischen zwei Zellen hinein.
in on a conversation between two cells,
to something called a spike.
das sich "Spike" nennt.
or your brain or your teachers' brains,
von einem von uns, sondern
friend the cockroach.
very similar to ours.
die Funktion ihres Gehirns,
about how their brains work,
about how our brains work.
in some ice water here
Greg: Ja ...
Greg Gabe: Yeah ...
they become the temperature of the water
die Temperatur des Wassers an
so they just basically "chillax," right?
im Prinzip einfach, OK?
about what we're going to do,
was gleich passiert.
vornehmen, um das Gehirn zu verstehen.
to understand the brain.
has all these beautiful hairs
that is going to send information
Eine Kakerlake zu fangen
it's hard because they can feel you coming
bevor ihr da seid, und wegflitzen.
they start running.
sausen also zum Gehirn
this information up to the brain
mit elektronischen Botschaften darin.
with electronic messages in there.
wir das aufnehmen.
by sticking a pin right in there.
of a cockroach --
Sie sind aus Metall und
die da vorbeiwandert.
this electric message is going by.
hoffentlich könnt ihr das sehen.
let's see if you guys can see this.
stecke es in eine Erfindung von uns –
that we came up with
teurer Ausrüstung im Labor,
equipment in a research lab,
an der Schule machen,
in your own high schools,
Ich schalte es jetzt an.
and turn this on.
(Geräusche feuernder Neuronen)
das schönste Geräusch der Welt.
sound in the world.
is doing right now.
dieses Regengeräusch.
making these raindrop-type noises.
das wie ein Stachel – ein "Spike" – aussieht.
the axon looks like a spike.
wie sie aussehen.
looks like in just a brief second.
wir einen Durchschnitt kriegen.
That's an action potential.
in your brain doing this right now,
genau jetzt in euren Gehirnen.
was ihr hört, was ihr seht.
about what you're seeing, hearing.
Informationen über Windstöße wahrnimmt.
about vibrations in the wind.
and hear if we see a change.
wenn wir es anpusten?
ob ihr etwas hört.
if you hear anything.
with a little pen here.
mit dem Stift hier an.
Das war lange nicht bekannt.
in neuroscience to understand this.
desto mehr Spikes gibt es
the more spikes there are,
ins Gehirn. So nehmen wir wahr.
is coming up to your brain.
experimentieren.
an experiment with electricity.
elektrischer Impulse experimentieren.
only taking in electrical impulses,
etwas Elektrisches
something that's electric
I'm going to plug them onto the cockroach.
stecke sie in die Kakerlake.
in meinen iPod.
I'm going to plug in into my iPod.
in euren Ohren funktionieren?
work in your ears?
in your phone, or iPod, right?
kleine Magnete in den Stöpseln.
into these magnets in your earbuds
und so hört ihr.
and allow you to hear things.
that our brain uses,
wie in unserem Gehirn.
zum Kakerlakenbein schicken
wir Musik in die Kakerlake einspielen.
when we play music into the cockroach.
Was geht hier vor?
It's moving on the bass.
Lautsprechern wissen,
am größten sind.
are the biggest speakers.
have the longest waves,
Diese haben die höchste Spannung
dass sich das bewegt.
these things to move.
erzeugen Elektrizität.
that are causing electricity.
einen Helfer auf die Bühne.
another person out on the stage here
happened in the history of mankind.
Menschheitsgeschichte.
ein Kakerlakenbein.
think about neuroscience
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.
