We prototyped by CAT scanning the brain out of this animal.

But humans are different.

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

Bullet from the frontal lobe of your rear admiral.

The bell curve shows 150 controls, and what is being looked at is the difference between the right and the left frontal lobe.

So you have the prefrontal cortex here,

If you look at the first slide there, that's the temporal lobes, frontal lobes, parietal lobes, OK the lobes that constitute the brain.

Psychosurgery. Procedures like the transorbital lobotomy.

To hear it, you'll need a frontal lobe and things with names like colliculus and temporal gyrus, but you won't have them anymore because they'll just be soup.

Ever heard of transorbital lobotomy?

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.

You're a smart man, Muller.

The following in your head!

You were the boss, right?

Just very simply, the three parts of the brain the frontal lobe, where you focus your attention and concentration you have the temporal lobe, where you form images and keep memories and the posterior part of your brain, which contains the cerebellum, which controls motion and the brain stem, where you have your basic maintenance functions,

This is a roughly normal scan, showing equal distribution of energy.

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

Right, right?

I used to think you had a brain, man.

The front part of my head.

Use your fuckin' hand.

This is the work of Dr. Bruce Miller.

So one part is the parietal cortex which is very well known to control the orientation of attention.

It peaks in early adolescence.

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

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

So here this is the car seat.

Do a little thinking next time, before you use it.

You report to the flight deck.

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

So one, two, three, four, five, six, seven 0's.

I shoot you through the brain.

Bow your head before me.

Dance really can make science easier to understand.

I'm guessing that's yours.

He was clearly embarrassed.

He runs a garage. That makes you smarter.

Heads, you get to keep your head.

Are you out of your fucking mind?

Take Sean, who prefers blue tasting food, such as milk, oranges, and spinach.

Now look at that beautiful, big, old forehead on the Homo sapiens skull.

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

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.

Why are you even bothering to think about her? Just handle things the way you always do.

You're flying off the handle. Always taking things for granted.
