It's important if you try to model this.

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

Here's another example.

So you have the prefrontal cortex here,

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

The reason is, they're treating other people like a computer, and the brain is too.

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

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

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.

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

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

Their motor cortex is partially exposed at the back of their neck.

It peaks in early adolescence.

The frontal lobe, the neocortex, the human part that doesn't come back.

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.

And one of the main reasons our brain got so big is because it got a new part, called the frontal lobe.

So what is the picture that we get here?

So for example we can look to the cortical area that represents input that's controlling the posture of the monkey.

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

One of the brain regions that changes most dramatically during adolescence is called prefrontal cortex.

We tapped into your cerebral cortex... allowing you to relive your memories in vivid detail.

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.

And you see activity in some regions we've seen today, medial prefrontal cortex, dorsomedial, however, up here, ventromedial prefrontal cortex, anterior cingulate, an area that's involved in lots of types of conflict resolution, like if you're playing Simon Says, and also the right and left temporoparietal junction.

There's the skull, there's my drawing of a skull.

The main unit will then go inside the brain.

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

or cortical visual impairment.

one last question.

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

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

(Laughter)

Cortical fluctuation. It could trigger a seizure.

This was a woman who didn't have trouble with her eyes, but the visual parts of her brain, a little tumor in the occipital cortex.

PART TWO

Roof 43, let me know when you have visual.

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.

I thought it was all graphics.

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