Bill Nye the Science Guy - S02E14 The Brain (2023)


Bill Nye the Science Guy (The Brain)


Fools fools they laughed at me.

Rulz inertia is a property, Bill Nye.

The Science Guy is brought to you by the brain without it.

You wouldn't be able to understand what I'm saying and it wouldn't be any good for reason hearing.

And why are animals and like all animals we control everything we do with our brains, whether we're talking breathing, just sort of thinking about stuff.

We do it all with our brains.

Now, compared to the size of our bodies, humans have the largest brain of any animal on earth.

We may have heard people say, you know, you only use 10% of your brain.

Well, that's, not true use a hundred percent of your brain all day and all night, even while you're asleep you'll do it on with your brain, I suppose I want to do this or decide to do this I'm using my brain, throw catch picking up off the floor, it's all done with your brain.

Your brain is a group of special cells that can send plenty electrical signals all over your body through something called a central nervous system, it's a bundle of nerve cells that goes inside your spine.

And then branches out all over the place.

Your cells are able to send tiny electrical signals with very small.

Chemical changes it's kind of wild that's.

What happens every time you move or think so let's say that I've been you and me? Yeah, you asked me to be a picture of a tree.

Well, do it's bad I think about and I.

Remember what a tree looks like? And you look at that, you think, well, I guess that looks a little bit like a tree? See? It reminds you of a tree? Yeah, a tree think about what happened I had to understand that you asked me to draw a picture of a tree.

Then I had to remember what a tree looked like then I had my brain used my central nervous system to make my hand paint a tree.

Now look we're, both thinking of trees and that's.

Just one image.

That's just one tree, one piece of information just think about all the things that happen to you all the things that you can plan think of all the information you can store in here.

It's wild, it's, amazing it's.

Wild have you ever made a great pet that's surprised, even you have you ever memorized a speech by repeating it over and over have you ever laughed when someone tickled you, you will and the system that we'll be bringing it to you.

You can measure your brains reaction time just have someone drop a ruler between your fingers, 19 centimeters.


It only takes like a split-second for your eyes to send a message to your brain.

And for your brain to think about what's happening long enough to tell your hand to pick up the ruler.

So like the further, the ruler falls, the slower, your reaction time check it out, though, if you drop the ruler through your own fingers, you respond a lot faster.

See when you open your top hand, nerves carry a message in one hand to the bottom of your brain, which automatically tells your other hand to close since you don't have to see the ruler drop your action.

Time is much better.

You try it top never mind brain spinal cord nervous system control all of an animal's body functions, even playing a videogame requires all three to work in perfect unison.

There was something I was gonna say it's, right on the tip of my tongue.

Oh yeah, I was gonna talk about memory scientists like to think of humans as having four types of memory.

We have our short-term memory that's where you say things over and over again.

So you remember them, you don't call Steve and call Steve call that's.

Why a lot of times it's easier to write stuff down.

Then we have our long-term memory that's.

What we remember important events or things that we do over and over again.

And then we have our ancestral memory now, that's, where animals remember how to do stuff right when they're born like birds, remember how to build nests or humans, remember how to get milk from their mom or from a bottle.

And then we have our eidetic memory.

Now our eidetic memory is also called photographic memory.

You know, sometimes you can remember where a picture was on a page in a book, well, that's your identic memory.

So there you have it the four types of memory there are shot to short-term memory long long, long-term memory, an ancestral memory and eidetic memory.

Yeah, yeah.

Can you remember all that everybody and welcome to this old brain, I'm, Bob, Lea, come on this way.

And watch that whole hand, we're gonna work on the wiring of the central nervous system.

This all right over here, what's the story on the wiring here.

Well, it seemed this little brain had some damage inflicted upon it.

A while back, they probably weren't wearing a helmet, that's, tough, that's, tough.

What do we do here? Well, we have to hook these wires back up.

You know, if the wiring shot on the central nervous system, it makes it really hard for the arms and legs to receive that message from the brain, the whole body, really basically, yes.

It looks like we need a log job in here to someone let you get back to work there all right.

Okay, Bob I'll.

Meet you down in the module.

A little later, hi I'm, Charles, Green and I'm.

Both the doctor and a brain scientist at the University of Washington.

The brain is very complex.

And each of the regions subserve, a different function.

When I'm out on the basketball court, I use the cerebellum, which is this part of the brain to keep my balance when I'm running around opponents when I wake up in the morning, I can smell my breakfast using this part of the brain, which is the olfactory cortex, the century' motor cortex is this area here it's, not very well defined but it's, the part of the brain that allows us to move and to feel.

And over here on the side is the temporal lobe.

And inside of this area here on the temporal lobe is the auditory cortex, which allows me to hear inside of the cortex, this part of the brain, but thousands of tiny brain cells about the size of a pinpoint and they communicate with the rest of the body by sending their processes out of the brain and into the spinal cord, the spinal cord connects with all of the muscles in the body and tells them when to move using all of this amazing equipment allows us to study the electrical activity of individual brain cells.

And in this way, we're beginning to understand how the brain as a whole functions, you know, brains are really cool.

This combination of cells seems to have no limitations, unlike the most spectacular electronic brain.

This machine can think for itself extra read all about it.

Rain is falling to fittin skull.

No wonder your brains in the headlines think of all the information that can store think of your brain as a newspaper it's, folded just think of all the words pictures and ideas in here.

They take up a lot less roomm.

When the newspaper is folded, you know, a newspaper has a lot of information just look at it.

All all those pages in just one Sunday newspaper, just think of all the information that must be in your brain, it's enormous.

But it doesn't take up too much room because it's folded.


My name is Martita, Neron, I'm, a filmmaker.

Well, actually, I make TV shows for kids.

You know that wacky scientist with a bow tie that was mine when I heard about spinal cord store, I jumped at the chance of capturing the inner workings of the brain.

But enough of my gabon, what do you say let's rock? This is spinal cord.

No, the trouble were about to go home.

Hey, she's exploded that's agreement.

You got on the donkey.

What do you mean? He just exploded, how we're gonna communicate with our fans spiral cold must remain intact upon musics to be relayed from our brains to the dancing for days Hey.

So right, we just turn the answer powder.

Bernards are there already turn up to ten well, using your gonna turn them up to 11 that's, what Nick come on the skin of an orange and the rind of a melon protect the soft squishy fruit inside your brain is protected to by thick, heart, boom, but sometimes even your skull, isn't enough protection.

So use your head wear a helmet look didn't, even hurt it, good as new so Bob when the wiring gets really screwed up.

Yeah, watch this.

Okay, the brain interprets and stores information so much information that if your brain weren't folded, it would never fit in your skull, fully makes it fit that's smart.

What let's say we wanted to take a picture of a brain let's say, my brain, well, we couldn't very well, use a camera could we because it wouldn't fit? Yeah, I guess not.

But we can take an MRI a magnetic resonance image.

The way this works is there's, a very powerful magnetic field going this way.

And then a radio wave goes through like this.

And the two of them working together generate this crisp image, it's really cool it's in here.

Oh, you can't.

Come in, you can't, come in because there's a very powerful magnet, and it would ruin the videotape also it's really loud.

Here we go looks like you did fine they're coming up and they're, very nice and steady where's.

His brainstem see here's one eyeball, the optic nerve starting to his ventricles hair, white and gray matter, the little lining that's around the brain.

This is his pituitary.

This is a carotid artery coming up a major major artery.

That leads the brain.

Should we get him out of there? Right? Here is the snake's brain.

This is a chicken brain.

This is a rabbits brain.

This is a turtle brain and user times.

This is a human brain.

Just like the one that I have in my head, except mines like the size of my fist.

This part right here is where it connects down to your spine like around here's where the touches.

And the motion is down below your eyesight.

Your sons vision is the one that you use the most the left side of the brain, controls the right side of the body and the right side of the brain controls the left side of life.

Look at all those cute little brain cells.

Look at them, see you and she and I all about the same number of brain cells.

They have the same number of brain cells when we're born as when we're grown-ups about 100 billion see we never get any more now, if you cut your finger, you can put a bandage on it and it'll heal in a few days, if you break your leg, you can put a cast on it and it'll heal in a few weeks.

But it doesn't work that way with your brain cells, we never grow new ones.

So you can damage your brain cells by drinking alcoholic beverages, taking drugs or crashing your bike when you're not wearing a helmet.

So be careful think about your brain cells are you thinking about here's, an awesome way to improve your memory, pick a room in your house? Oh and I know, the perfect place? Okay, let's.


The prop room, okay, that's been exactly one minute looking around the room and memorizing, everything you possibly can.


Now you leave the room and draw a picture of everything you possibly can.

Remember, hi, I'm, Jerry, Andrus, I'm, very interested in how our human brains work and I'm standing inside what I call box impossible.

And if you'll look maybe you'll see that there seems to be something wrong with it.

Here is a picture of just ordinary, fluffy clouds.

And now I'm going to spin this tri-zone space, warper and I'm going to have you stare right at the center of it for 20 seconds.

You keep staring right at the center of this, try some space work now we're going to show you that steel cloud picture again, but you'll see that it looks like it's, boiling there's nothing moving about at all.

It just looks like it's boiling, because you've been staring at the space warp or disk got it figured out yet here's.

Another one, this represents two large breasts, that's when I move them, they look like they're moving independently.

Now, I have a straight tube here, I'm going to push this straight tube through this nut and you'll see that it looks like it has to bend in the middle to go through the other one see the straight tube looks like it's bent in order to go through the other one I, hear again, your wonderful brain has just shown you something different than what it really is.

This is made out of plastic.

And you are looking at the inside with this a wonderful brain, interprets something different than it actually is, but it doesn't mean that it's made a mistake.

It took the information it had, and it did its best job here.

Watch this look it's.

Not a box at all I was just standing in the corner of this framework.

And you can see it has no resemblance to a box at all and you're a wonderful brain interpreted that picture on the retina has a box when I'm talking the part of my brain called the cortex, it's sending millions of signals to my mouth and tongue.

So that I can form words and make sentences.

Also this valid answer of science is sending millions of pieces of information all over his body, so that he can plie and relevé and eh, not bad.

Yo, your brain is as active when you're asleep as it is when you're awake, in fact, let's run a test right now.

Yeah, little shut-eye it's, not bad.

The nobel prize for the most scientific like plane goes to such wacky, science guy.

My name is Chris and I'm, an ultra runner.

And after 90 miles, which my brain that keeps me determined to finish the race, hopefully this summer I'll finish a 100-mile race, if you're bringing the news of your body once your body's into, you know, get you there? But your brain is the one that really gets you there.

If you don't think you can do it, you can't do it.

But if you think you can you can do anything.


One last time.

This is a hot frying pan.

This is your brain reacting to a hot frying pan, put your brains for shantae.

No it's got the spinal cord to help with the work and don't.

You be thinking back to the nervous when it comes to memory your brains.

No snob cuz.

Fine information is a serious job.

Long time, short time, that's, that's, Troy and I, get it with four types of memory.

It gets pretty hectic, not the time of the song where we say goodbye gotta make room for the big brain bill so pay close attention and use the refrain your most important organ, what a great what a brain, what a mighty good brain.

Everything looks okay.

That's my brain and that's our show thanks for watching if you'll excuse me and I've got millions of synapses to Ford and neurons to fire.

See you produce an association with the National Science, Foundation, science, science, no it's, not science, it's science, I know, Sawyer's Gidget cerebral cortex, which is connected to your neurons and all the other stuff this side you wanna go now, he's, fine code, video, some ganglia this wiring, sharper watch.

What happens when you do this.
