That's the small lobe, and then that's the big lobe like that.

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.

In her right frontal lobe.

So you have the prefrontal cortex here,

Prefrontal cortex is an interesting brain area.

Then you have another one that has a big lobe like that and a small lobe in the back.

Really, consciousness is seated in the frontal lobe.

And you do that by measuring the relative activation of the left prefrontal cortex in the fMRl, versus the right prefrontal cortex.

And then you have one where the big lobe is pointing straight up, and it has a small lobe going down.

The arrows indicate peak gray matter volume in prefrontal cortex.

Bullet from the frontal lobe of your rear admiral.

Let's say this is the big lobe that is kind of pointing near us, and then it has a small lobe in the back.

And he studied Alzheimer's patients that had frontal temporal lobe dementia.

We have a recent rectangular transection to the left occipital lobe.

We've got the occipital lobe so we can actually see the world.

We got the temporal lobe so we can actually hear the world.

Michael needs an operation to remove a tumor from his temporal lobe.

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

Here, they're parallel. p orbitals are parallel to each other, and you see that they overlap on this kind of top lobe here and in this bottom lobe here.

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

And in particular, one area of the temporal lobe is called the fusiform gyrus.

And you can see here, he's starting to get more energy into the frontal lobe.

And the temporal lobe hallucinations are all sense hallucinations, full of feeling, full of familiarity,

So we had this focal area called the medial prefrontal cortex that went way up in activity.

It's pushing up against his temporal lobe and it will kill him if it's not removed.

We know that if you stimulate the temporal lobe, you can produce a feeling of out of body experiences, near death experiences, which you can do by just touching an electrode to the temporal lobe there.

We had this broad patch of area called the lateral prefrontal cortex that went way down in activity,

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

When images are formed, a higher part of the visual cortex is involved in the temporal lobe.

Michael needs an operation to remove a tumor from his temporal lobe, and he needs it now.

like the dorsal lateral prefrontal cortex or the superior temporal gyrus, there is a profound loss of gray matter.

In very short, people who have more activity in the right side of the prefrontal cortex are more depressed, withdrawn.

You can kind of imagine a three legged stool, and then its small lobe will come out like that.

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.

The gene heightens normally occurring connections between the taste area in his frontal lobe and the color area further back.

This is an area in the prefrontal cortex, a region where we can use cognition to try to overcome aversive emotional states.

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

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

One of the big surprises is how limited our attention is, and it comes back to how small and fragile the prefrontal cortex is.

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

Let's say this is an sp3 hybridized orbital, and that's on this atom and this is kind of this big lobe right there.

You have the middle area, where the temporal lobe might be, in here, and the posterior portion, where the maintenance functions are in the back.

So in my lab, we bring adolescents and adults into the lab to have a brain scan, we give them some kind of task that involves thinking about other people, their minds, their mental states, their emotions, and one of the findings that we've found several times now, as have other labs around the world, is part of the prefrontal cortex called medial prefrontal cortex, which is shown in blue on the slide, and it's right in the middle of prefrontal cortex in the midline of your head.

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,

Well, we know exactly where it happens, in the temporal lobe, right across, sort of above your ear there, in a little structure called the fusiform gyrus.
