how does the heart work,
hoe het hart werkt,
dat het een pomp is.
om in koolstofdioxide.
oxygen for carbon dioxide.
it's hard to understand
bekijken om het te begrijpen.
at a brain and understand what it is.
geen pomp, geen airbag.
not a pump, not an airbag.
in your hand when it was dead,
als het dood was,
you have to go inside a living brain.
moet je een levend brein ingaan.
the brain is electrical and it's chemical.
het is elektrisch en chemisch.
100 billion cells, called neurons.
zogenaamde neuronen.
with each other with electricity.
via elektriciteit.
in on a conversation between two cells,
tussen twee cellen afluisteren.
to something called a spike.
or your brain or your teachers' brains,
het jouwe of dat van je leraar opnemen,
friend the cockroach.
de kakkerlak.
very similar to ours.
op het onze lijkt.
about how their brains work,
over hoe hun brein werkt,
about how our brains work.
in some ice water here
Greg Gabe: Yeah ...
Greg Gage: Ja ...
they become the temperature of the water
nemen ze de watertemperatuur aan.
so they just basically "chillax," right?
en 'chillaxen' dus.
about what we're going to do,
to understand the brain.
om het brein te begrijpen.
has all these beautiful hairs
mooie haartjes en prikkertjes.
that is going to send information
it's hard because they can feel you coming
want ze voelen je komen
they start running.
door naar het brein,
this information up to the brain
with electronic messages in there.
met elektrische boodschappen.
door hier een naald in te prikken.
by sticking a pin right in there.
of a cockroach --
van een kakkerlak uittrekken --
ze groeien terug --
boodschap op die voorbij komt.
this electric message is going by.
let's see if you guys can see this.
Even checken of jullie dit zien.
that we came up with
equipment in a research lab,
dure toestellen in een lab.
in your own high schools,
and turn this on.
sound in the world.
is doing right now.
die regendruppel-geluidjes maken.
making these raindrop-type noises.
the axon looks like a spike.
er als een 'piek' uitziet.
looks like in just a brief second.
over een seconde.
Dat is een actiepotentiaal.
That's an action potential.
in je brein die dit nu doen:
in your brain doing this right now,
about what you're seeing, hearing.
over wat je ziet en hoort.
about vibrations in the wind.
over trillingen in de wind.
and hear if we see a change.
en horen of er een verandering is.
if you hear anything.
of jullie iets horen.
with a little pen here.
in neuroscience to understand this.
even over gedaan om dit te snappen.
the more spikes there are,
hoe meer pieken je krijgt.
is coming up to your brain.
an experiment with electricity.
van experimenteren met elektriciteit.
only taking in electrical impulses,
niet alleen elektrische impulsen ontvangt,
something that's electric
als ik iets elektrisch inschakel
I'm going to plug them onto the cockroach.
en steek ze in de kakkerlak.
en steek dat in mijn iPod,
I'm going to plug in into my iPod.
work in your ears?
werken in je oren?
in your phone, or iPod, right?
into these magnets in your earbuds
naar de magneten in je oortjes
and allow you to hear things.
waardoor je dingen kan horen.
that our brain uses,
de stroom die ons brein gebruikt.
naar onze kakkerlakpoot sturen.
als we muziek de kakkerlak insturen.
when we play music into the cockroach.
Daar gaan we.
Hij beweegt op de bas.
It's moving on the bass.
autostereo's hebben,
de grootste zijn,
are the biggest speakers.
met de grootste golven
have the longest waves,
these things to move.
die voor elektriciteit zorgen,
that are causing electricity.
another person out on the stage here
happened in the history of mankind.
in de geschiedenis van de mensheid.
op een kakkerlakpoot.
think about neuroscience
denk dan aan neurowetenschappen
the neuro-revolution.
kunnen ontketenen.

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.
