It's important if you try to model this.

This triggers the pituitary gland, a pea sized gland found at the base of the brain, to release adrenocorticotropic hormone which then stimulates the adrenal gland sitting on top of the kidneys to release cortisol, the major stress hormone.

Kidney. Kidney. Kidney.

The hypothalamus, the master controller of your hormones, releases something called corticotropin releasing hormone.

So you have the prefrontal cortex here,

These are the surfaces the monkey is using to manipulate the tool.

And we just... We have to accept it.

It's also, by the way, a characteristic of certain kinds of brain damage.

They're there because there's this very close interaction.

It peaks in early adolescence.

Cortical Surface Reconstruction and Visualization

We're only going to talk about three of them.

So here's how it looks. Look at the region there.

So what is the picture that we get here?

Our newest brain, our Homo sapien brain, our neocortex, corresponds with the what level.

It goes to the nucleus accumbens, all the way up to the prefrontal cortex, orbital frontal cortex, where decisions are made, high level.

That's where the difference is.

But I have confirmed that he's got an outer layer of protein polysaccharides.

Ceramides. They act as a signaling molecule in skin.

So this is a model of the human brain, and this is prefrontal cortex, right at the front.

You probably know, if you've been paying attention to some of the science literature that you can now take a skin cell and encourage it to become a liver cell or a heart cell or a kidney cell or a brain cell for any of us.

The main unit will then go inside the brain.

It's keeping me standing. It's involved in coordinated movement.

or cortical visual impairment.

Where is she?

What's the matter with her?

Let's say you wanted to read something out loud.

Here's another example.

Those patterns are risk factors for developing one of these disorders.

(Laughter)

Cortical fluctuation. It could trigger a seizure.

Well, so what I read on WebMD

In red is an area that's active in the prefrontal cortex, the frontal lobe of the brain, and in blue is this area that was deactivated.

And if you closed your eyes you'd be able to mentally navigate it.

It's called the hippocampus.

Yeah, but it's the chemicals in the grape skins that do it.

Females, like males, have in our bodies something called the adrenal glands.

I have kidney trouble.

I thought it was all graphics.

Our newest brain, our Homo Sapien brain, our neocortex, corresponds with the what level.

You know all about imaging, right, ultrasound imaging.

Very quickly they told me,

So that's the part of the brain that is activated when you give a word to something.

If you do this it turns out, the auditory cortex will learn to see.

And what pattern do you see here?
