So you have the prefrontal cortex here,

(Laughter)

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

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

It peaks in early adolescence.

And in the Charles Bonnet syndrome, you don't go to those higher levels.

It's important if you try to model this.

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

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

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

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

And instead of getting normal perception, you're getting an anarchic, convulsive stimulation, or release, of all of these visual cells in the inferotemporal cortex.

Here's the auditory cortex, and this is the sound of her voice, or the things, the wise things she said to you.

EEG acquisition system.

The crown you bore aloft

The pattern is that those people, every one of them I looked at, who was a murderer, and was a serial killer, had damage to their orbital cortex, which is right above the eyes, the orbits, and also the interior part of the temporal lobe.

Scalp Hermann.

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

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

My scalp is very itchy.

That would skin the scalp.

A fire that melts the hide.

snatching away the scalp,

Flaying off the scalp skin.

Taking away (burning completely) the head skin!

It strips away the scalps.

that will strip off the scalp.

Eager to roast

which strips away the scalp.

It snatches away by the scalps,

A remover of exteriors.

will strip off the flesh

Dragging by the head,

stripping away his skin,

Plucking out (his being) right to the skull!

I have dry scalp.

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

We thought we could adapt it for the brain.

Subcutaneous injection marks.

Whale blubber.

And as they follow them over 5 years comparing them to age match controls, you can see that, particularly in areas

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

It's tearing his scalp.

Well it turns out there is a way to measure happiness in the brain.
