This was originally seen as a system that was the pleasure system of the brain.

And the memory system is sitting over the sensory part of the brain.

In over 175 societies, people have left their evidence of this powerful brain system.

And when you tamper with one brain system, you're going to tamper with another.

This heat map is going to show you how the brain of the system works.

We have a special brain system that lets us think about what other people are thinking.

The one physical system, the brain, contains an accurate working model of the other the quasar.

That brain system the reward system for wanting, for motivation, for craving, for focus becomes more active when you can't get what you want.

But now we try to understand that in terms of the development of a part of their brain called the limbic system, so I'm going to show you the limbic system in red in the slide behind me, and also on this brain.

It s a neural system that s wired up to reward the brain for doing a grubby clerical job.

But the researchers feel quite confident that they can also work in the brain and central nervous system.

And he knew from our work that if you go and do something very novel with somebody, you can drive up the dopamine in the brain, and perhaps trigger this brain system for romantic love.

But when you exercise them, any given muscle adds strength to the whole system and that applies to your brain too.

And the third brain system is attachment that sense of calm and security you can feel for a long term partner.

The pleasure system, as you see, which is the internal opiates, there is a hormone oxytocin, is widely spread throughout the brain.

Brain magic. What's brain magic all about?

For those of you who aren't familiar with memetics, a meme has been defined as an idea that replicates in the human brain and moves from brain to brain like a virus, much like a virus. The way a virus works is it can infect and do the most damage to someone who has a compromised immune system.

You're more complicated than your brain. You've got a brain.

What if we could just turn off that brain for a brief amount of time, until the seizure dies away, and cause the brain to be restored to its initial state sort of like a dynamical system that's being coaxed down into a stable state.

If that single stability system, that brain that flies that aircraft, fails, or if the engine fails, that vehicle crashes. There is no option to that.

And in fact, sometimes I feel a little sorry for the chicken on my dinner plate, when I think of how intense this brain system is.

And then finally, to show that some of the differences between people, in how we judge others, can be explained by differences in this brain system.

And the first thing it does in implanting on that rock, which it never leaves, is to digest its own brain and nervous system for food.

If those diseases where tissues are deteriorating for example Alzheimer's, where the brain, the brain cells, die and we need to restore new brain cells, new functional brain cells what if we could, in the future, use cancer? A tumor put it in the brain and cause it to differentiate into brain cells?

The old brain is still there. You still have that alligator brain.

The new brain is actually kind of easier than the old brain.

When we think of brain, we of course imagine our own brain.

Brain Party

But maybe, in this chap, that wire that goes from the amygdala to the limbic system, the emotional core of the brain, is cut by the accident.

A neuron under the microscope is very elegant with little things sticking out and little things over here, but when you start to put them together in a complex system, and you start to see that it becomes a brain, and that brain can create intelligence, what we're talking about in the body, and cancer is starting to model it like a complex system.

And that's just a mouse brain it's a lot smaller than a human brain.

And after all, we are our brains. My brain is talking to your brain.

So faking your brain going wrong is evidence that your brain has gone wrong.

The idea of replicating ideas ideas that replicate by passing from brain to brain.

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

And I'm going to show you a system that we designed to model the retina, which is a piece of brain that lines the inside of your eyeball.

Here's my brain.

Rebuilding the Brain

And so, what we can see is that over the course of childhood and even into adolescence, both the cognitive system, our mind's ability to think about other minds, and the brain system that supports it are continuing, slowly, to develop.

But all of this sensory information has to be processed by a brain, and yes, indeed, flies have a brain, a brain of about 100,000 neurons.

Now if there's a gut brain, we should also learn to talk with this brain.

And furthermore, that nervous tissue brain gets cancer, and brain cells are also terminally differentiated.
