0:00:530:00:54

Hm... Oh, hello there.

0:00:550:00:58

I've been trying to solve this puzzle.

0:00:580:01:01

I'm trying to find a path

0:01:010:01:02

from the outside of the maze to the middle,

0:01:020:01:05

but every time I choose one of the paths, I come to a dead end.

0:01:050:01:09

-Thinking's making my brain hurt!

-BEEPING

0:01:090:01:13

Oh! I hear a beep, I see a flash. I wonder what they're going to ask.

0:01:130:01:18

-ALL: Hi, Nina!

-Hi, guys!

0:01:230:01:26

We've got a question for you.

0:01:260:01:28

Why do we have a brain?

0:01:280:01:30

That's a great question. Why do we have a brain?

0:01:300:01:34

I've been using my brain a lot today.

0:01:340:01:37

Come to my lab and we'll do some experiments to investigate.

0:01:370:01:41

ALL: See you soon, Nina! Bye!

0:01:410:01:45

Bye!

0:01:450:01:47

I'm going to need some help and I know just who to ask.

0:01:470:01:51

OK, Neurons, time to get to work.

0:01:510:01:53

ALL: Neurons at the ready, Nina.

0:02:100:02:12

Today's question is, why do we have a brain?

0:02:120:02:15

Which Neuron will be most useful in helping us find the answer?

0:02:150:02:20

ALL: Me! Me! Me!

0:02:200:02:23

Will it be fabulous Felix?

0:02:230:02:26

I can help so very much if you need the sense of touch.

0:02:260:02:29

Will it be beautiful Belle?

0:02:290:02:31

I send messages to brain from ear. If there's a sound, I'll help you hear.

0:02:310:02:36

Will it be lovely Luke?

0:02:360:02:38

For looking and seeing, day or night,

0:02:380:02:40

I'll help you with your sense of sight.

0:02:400:02:43

Will it be awesome Ollie?

0:02:430:02:45

If it's pongy or whiffy but you can't tell,

0:02:450:02:47

my messages help your sense of smell.

0:02:470:02:50

-Or will it be baby Bud?

-Sour, salty, bitter or sweet.

0:02:500:02:54

I'm your taste buddy whenever you eat.

0:02:540:02:56

BEEPING

0:02:560:02:59

-It's all Neurons!

-Yippee!

-Yes!

0:02:590:03:02

ALL: Go, Neurons!

0:03:020:03:04

Go, Neurons! Go, Neurons! Go, Neurons! Go, Neurons!

0:03:040:03:07

Go, Neurons!

0:03:070:03:09

All Neurons hip-hop-happy to help, Nina.

0:03:090:03:12

Today's question is, why do we have a brain?

0:03:120:03:15

Our brain uses all five of our senses -

0:03:150:03:17

our sight, hearing, smell, taste and touch.

0:03:170:03:20

So, I'm going to need help from all the Neurons!

0:03:200:03:23

Right, I'd better get the lab ready.

0:03:230:03:27

Shahbaz likes snakes, Shay likes swimming and Kian loves bacon.

0:03:290:03:34

But all they want to know why we have a brain.

0:03:340:03:37

So, today, Shahbaz, Shay and Kian become the experimenters!

0:03:370:03:42

-Hi, guys!

-ALL: Hi, Nina!

0:03:440:03:48

Welcome to my science lab. Come on in.

0:03:480:03:50

Now, your question is,

0:03:500:03:52

why do we have a brain?

0:03:520:03:54

Superb question! Why do you want to know?

0:03:540:03:57

We know we have a brain.

0:03:570:04:00

But we're not sure what it does.

0:04:000:04:03

Our brain is the most amazing part of our brilliant bodies.

0:04:030:04:07

First, we're going to use our senses.

0:04:070:04:09

ALL: Whoop-whoo! A senses experiment! We're ready, Nina.

0:04:090:04:14

-Have you all brought your brains with you today?

-Yes, Nina.

0:04:140:04:18

Could you pop them out onto the worktop so we can have a look?

0:04:180:04:22

We can't do that, Nina.

0:04:220:04:24

Of course! Our brains are inside our heads.

0:04:240:04:28

So, our brains live here,

0:04:280:04:30

inside our hard, bony skull, and that's where we should leave them.

0:04:300:04:35

So, for this investigation, I've made a pretend brain.

0:04:350:04:39

-How would you describe it?

-It's pink and soggy.

0:04:390:04:43

And it's like jelly.

0:04:430:04:45

Our real brains are grey in colour

0:04:450:04:48

but I've made this pretend brain out of pink jelly.

0:04:480:04:51

But it feels quite like our real brain.

0:04:510:04:54

Touch it and tell me what you think.

0:04:540:04:57

It's, like, soft.

0:04:580:05:00

Yes, our brains are quite soft.

0:05:000:05:02

It's lucky that we have these hard skulls to keep them safe.

0:05:020:05:06

If we were doing activities like cycling or skateboarding

0:05:060:05:10

what should we always wear?

0:05:100:05:12

A helmet.

0:05:120:05:14

Yes, we must always wear a safety helmet in case we fall.

0:05:140:05:18

But why are brains so important?

0:05:180:05:22

Well, our brain is the control centre for our body,

0:05:220:05:25

which means our brain tells our body what to do.

0:05:250:05:29

It sounds like a real bossy boots, Nina!

0:05:290:05:32

It is very bossy, Belle!

0:05:320:05:34

And there are lots of different parts to our bossy brain.

0:05:340:05:38

Different parts of our brain control different parts of our body.

0:05:380:05:43

Let's try an experiment. Can you boys do some star jumps. Go!

0:05:430:05:48

That's it!

0:05:490:05:51

Think carefully and tell me all the things your body is doing

0:05:510:05:55

so you can do those star jumps.

0:05:550:05:57

-We're jumping up.

-Arms are swinging out.

-Swinging out.

0:05:570:06:02

Yes, star jumps might feel simple to do,

0:06:020:06:04

but they mean doing lots of different things all at once.

0:06:040:06:08

OK, you can stop jumping!

0:06:080:06:10

And it was your brain that was telling your body

0:06:100:06:13

to do all these things.

0:06:130:06:16

And what else were you doing while you were jumping? Have a good THINK.

0:06:160:06:21

-Thinking.

-Yes!

0:06:220:06:23

You were using your brains to think of the answers.

0:06:230:06:26

You were listening and talking to me while doing the star jumps.

0:06:260:06:31

Different parts of your brilliant brains were telling your body

0:06:310:06:36

to do all these different things at the same time.

0:06:360:06:39

-How does our brain do this? Time for another experiment!

-Yay!

0:06:390:06:44

So, we know that our brain controls our body.

0:06:460:06:49

But how does it do this? It's a bit like these remote control cars.

0:06:490:06:54

The cars are like part of our body

0:06:540:06:57

and the remote controls are like our brain.

0:06:570:07:01

-Do you fancy ago?

-Yeah!

-Yeah!

0:07:010:07:03

LUKE: Look! That's amazing. Those cars are moving all by themselves.

0:07:100:07:16

Not quite, Luke.

0:07:160:07:18

The remote controls are sending invisible messages through the air,

0:07:180:07:23

telling the cars to move.

0:07:230:07:25

NINA CHUCKLES

0:07:250:07:26

When Shahbaz pushes the right button,

0:07:260:07:29

the car turns round to the right.

0:07:290:07:31

OK, boys, you can stop there.

0:07:310:07:34

Back over here.

0:07:340:07:36

It's a bit like how our brains send messages to our body,

0:07:360:07:40

telling it how to move.

0:07:400:07:42

When we did our star jumps,

0:07:420:07:44

our brain had to send messages to our arms and our legs

0:07:440:07:48

to tell them to move!

0:07:480:07:50

The messages were sent using something called motor neurons.

0:07:500:07:55

Hey, are you talking about us, Nina?

0:07:550:07:57

No, Bud, you're my sense neurons.

0:07:570:08:00

My motor neurons help me do things like walking and...

0:08:000:08:04

Whoop! ..picking things up!

0:08:040:08:07

My brain sent a message to my arm and hand to take this from you.

0:08:070:08:12

That message was carried by a motor neuron.

0:08:120:08:16

If I turned off the remote control, what would happen to the car?

0:08:160:08:21

-It won't move.

-Well, let's see.

0:08:210:08:24

Yes, the car doesn't move.

0:08:270:08:29

There are no messages being sent from here to the car.

0:08:290:08:33

It's the same for our brains - if the brain couldn't send messages,

0:08:330:08:37

we wouldn't be able to move how we want to.

0:08:370:08:40

Our brains need our motor neurons to talk to the rest of our body.

0:08:400:08:45

We need to find out more about what my sense neurons do

0:08:450:08:49

to help the brain too.

0:08:490:08:50

I know just the place

0:08:500:08:52

to DIG UP some information, so let's go!

0:08:520:08:55

EXPERIMENTERS: Yay!

0:08:550:08:57

Oh, goody! I love this bit.

0:09:000:09:03

I wonder where Nina is taking us.

0:09:030:09:06

Nina talked about digging up information.

0:09:060:09:09

Maybe it's a sandy beach by the sea.

0:09:090:09:11

I hope Nina's brought a yummy picnic!

0:09:110:09:14

OLLIE: Hm. It doesn't smell salty like the sea.

0:09:140:09:18

-BELLE:

-Listen up, guys - we're here! And I think I can hear an engine.

0:09:180:09:23

This is a really easy experiment.

0:09:250:09:28

All you have to do is move that huge pile of soil

0:09:280:09:33

from there, into the coned area.

0:09:330:09:35

-How does that sound?

-Difficult. It'll take ages.

0:09:350:09:39

Hey, what's that roaring, rumbling sound?

0:09:390:09:43

Wow, look at that! Ha-ha! Let's all wave to the driver.

0:09:460:09:50

Hello there!

0:09:500:09:51

NINA CHUCKLES

0:09:510:09:53

This digger is going to help us with our experiment.

0:09:530:09:58

Let's imagine that the arm of the digger is like our arm,

0:09:580:10:02

the scoop on the end is like a giant hand that's touching the soil

0:10:020:10:07

and the driver is like our brain.

0:10:070:10:09

The job of a sense neuron is to send messages to the brain.

0:10:090:10:14

So, using this walkie-talkie, send messages to the driver

0:10:140:10:19

to help him move the sand.

0:10:190:10:20

-How does that sound?

-It sounds like fun.

0:10:200:10:23

The scoop is touching the soil now. You can scoop it up.

0:10:230:10:28

-LUKE:

-That looks right to me.

0:10:320:10:34

That's it, you can drop the soil now.

0:10:360:10:39

Take a big scoop.

0:10:470:10:49

The digger is just like my hand,

0:10:520:10:54

feeling the soil and sending a message to the brain

0:10:540:10:58

to let it know it can pick it up.

0:10:580:11:00

And the brain is making the hand move.

0:11:000:11:02

You need to move it closer.

0:11:050:11:07

And...drop!

0:11:070:11:10

-FELIX:

-They're doing a marvellous job as sense neurons. Bravo!

0:11:120:11:17

Well done! You did a great job as sense neurons.

0:11:170:11:20

But it did take a long time and lots of messages to move the soil.

0:11:200:11:25

ALL: Yes, Nina!

0:11:250:11:27

Our neurons are a lot faster at sending messages than we are.

0:11:270:11:31

ALL: Yes! We're Nina's super-speedy sense neurons!

0:11:310:11:36

Messengers called sense neurons carry messages to our brain

0:11:360:11:40

to tell it what's going on.

0:11:400:11:42

And the brain then sends messages out to our body,

0:11:420:11:45

telling it what to do using our motor neurons.

0:11:450:11:49

We've dug up all the information we need to answer your question.

0:11:490:11:53

Let's go back to the lab.

0:11:530:11:55

EXPERIMENTERS: Yeah!

0:11:550:11:56

# Nina and the Neurons! #

0:11:560:12:00

Your question was, why do we have a brain? I think we answered it.

0:12:020:12:06

We discovered our brain controls our body and tells it what to do.

0:12:060:12:11

Different parts of our brain help us to do lots of things at once.

0:12:110:12:16

Our brain takes in information from messengers called our sense neurons

0:12:160:12:21

and tells our body what to do using our motor neurons.

0:12:210:12:25

-I hope that answered your question.

-ALL: Thanks, Nina! Bye!

0:12:250:12:29

Bye!

0:12:290:12:30

0:12:370:12:42

-Hearts beating.

-Lungs breathing.

0:12:420:12:44

-Fingers feeling.

-Mouths eating.

-And don't forget your brain!

Especially the star jumps!

0:13:400:13:43

Ah, it's been such a great day, man!

0:13:430:13:46

Invisible messages from the remote controls made the cars move.

0:13:460:13:52

Oh, I've had a brilliant day,

0:13:520:13:54

listening to the children sending messages to the driver.

Nina investigates why people have a brain with the help of her five sense neurons.

Experimenters Chevaz, Kian and Shay visit Nina in her lab and discover that the amazing brain is the control centre for the body - in fact, the bossy brain tells the body what to do! A game with some remote-control cars helps them to find out more. Nina explains that the remote controls are sending invisible messages to the cars, telling them to move. And the brain controls the body by sending invisible messages too.

These messages are delivered by something called motor neurons. But the body can send messages back to our brain too, using sense neurons. A final experiment with a giant digger, a big pile of sand and some walkie-talkies explains how this works!
