it's hard to understand
إنه شيء صعب الفهم
at a brain and understand what it is.
not a pump, not an airbag.
ليس مضخة ولا كيس هوائي،
in your hand when it was dead,
you have to go inside a living brain.
يجب أن تذهب إلى داخل دماغ حي.
the brain is electrical and it's chemical.
الدماغ كهربائي وكيميائي.
100 billion cells, called neurons.
تسمى الخلايا العصبية.

مع بعضها البعض عن طريق الكهرباء.

to something called a spike.

أو دماغك أو دماغ معلمك،
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 ...
غريغ غايج: بالفعل ...
they become the temperature of the water
يكتسبون حرارة الماء
so they just basically "chillax," right?
لهذا إنهم ببساطة "يسترخون،" صحيح؟
about what we're going to do,
to understand the brain.

that is going to send information
والتي ستقوم بإرسال معلومات
it's hard because they can feel you coming
إنه صعب لأنه يستطيع الإحساس بقدومك
they start running.
ويبدأ بالجري.
this information up to the brain

with electronic messages in there.
مع رسائل الكترونية بداخلها.
by sticking a pin right in there.
of a cockroach --
this electric message is going by.
هذه الرسائل الاكترونية ستمر.
let's see if you guys can see this.
لنرى اذا يمكنكم رؤية ذلك.
that we came up with
equipment in a research lab,
في المختبرات،
in your own high schools,
and turn this on.

making these raindrop-type noises.
the axon looks like a spike.
تشبه جهد السفاة.
looks like in just a brief second.
That's an action potential.
هذا هو جهد الفعل.
in your brain doing this right now,
في دماغك تقوم بهذا الآن،
about what you're seeing, hearing.
عن كل ما تراه وتسمعه.
about vibrations in the wind.
عن الإهتزازات في الرياح.
and hear if we see a change.
وسماع إذا كان هناك صوت.
if you hear anything.
إذا أمكنكم سماع أي شيء.
with a little pen here.
in neuroscience to understand this.
لفهمه في علم الأعصاب.
the more spikes there are,
يزداد أعداد جهد السفاة،
is coming up to your brain.
an experiment with electricity.
only taking in electrical impulses,
يأخذ فقط النبضات الكهربائية.
something that's electric
I'm going to plug them onto the cockroach.
وسأوصلهم بالصرصور.
I'm going to plug in into my iPod.
وسأوصلها بالحاسوب اللوحي.

in your phone, or iPod, right?
into these magnets in your earbuds
إلى المغناطيس في سماعات الأذن
and allow you to hear things.
وتسمح لك بسماع الصوت.
that our brain uses,
الذي يستعمله دماغنا،
when we play music into the cockroach.
إذا عزفنا موسيقى للصرصور
It's moving on the bass.

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.
