It's called a lobotomy.

Before, we only wore leaves on our bodies.

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

Really, consciousness is seated in the frontal lobe.

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

And you know, of course, what'll happen if you do a pre frontal lobotomy.

If you are happy about something, you'll go more to the left side.

If you have a bout of depression, you'll go to the right side.

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

If you see a comic movie, you go off to the left side.

Prefrontal cortex is an interesting brain area.

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

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

Now what does a pre frontal cortex do for you that should justify the entire architectural overhaul of the human skull in the blink of evolutionary time?

On your right hand side you can see a cucumber leaf, and on the middle, cotton leaf, and on the left a tomato leaf with these little stipplings.

And you see that in humans, because of the development of the pre frontal cortex, it's called.

It's been shown to promote pre frontal cortex development where a lot of cognition is happening.

Yevgraf, yes.

As for the top authority in this, other than Professor Itou of Chiba University, it's you.

So Beijerinck set out to discover the cause of tobacco mosaic disease.

In very short, people who have more activity in the right side of the prefrontal cortex are more depressed, withdrawn. They don't describe a lot of positive affect.
