It never left my brain.

This is a gamma radiation spec scan that uses gamma radiation to map three dimensional function within the brain.

So, what if we had Beck hooked up to a SPECT scan, something that could actually measure brain function?

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

I believe movement is the most important function of the brain don't let anyone tell you that it's not true.

If you pass the left brain, you have to take care of logic and common sense.

Data obtained from animal experiments show that harmful physiological changes result from the inability of the brain and body to respond to repeated stress with adaptive modifications in structure and function. Three brain areas the hippocampus, the prefrontal cortex, and the amygdala are particularly susceptible to pathological changes in size and function.

Now several people at this conference have already suggested that fruit flies could serve neuroscience because they're a simple model of brain function.

What you get is a highly selective loss of one function, with other functions being preserved intact, and this gives you some confidence in asserting that that part of the brain is somehow involved in mediating that function.

And of course, as I mentioned before, since we can now start to map brain function, we can start to tie these into the individual cells.

And a small part of my brain is thinking, 'That is so gross and really dangerous,' but most of my brain is thinking, 'Please let there be some smack left by the time it gets to me.

When I say we, I don't mean you, necessarily I mean me, and my right brain, my left brain and the one that's in between that is the censor and tells me what I'm saying is wrong.

As they do it, in the upper left is a display that's yoked to their brain activation of their own pain being controlled.

So that's good, but of course what we'd rather is have a way to interfere with function in this brain region, and see if we could change people's moral judgment.

And I'm going to talk about experiments that involve actually using this brain science, first of all to understand how it contributes to the loss of function as we age.

Well if I choose the left hand path, I can work out the forces required in one of my muscles as a function of time.

This is a tool that lets us pass a magnetic pulse through somebody's skull, into a small region of their brain, and temporarily disorganize the function of the neurons in that region.

Susana had engineered the fruit fly on the left so that just two out of the 200,000 cells in its brain expressed the light activated pore.

This function registers a completion function.

Form is function. Form is function.

Brain magic. What's brain magic all about?

The changes I showed you are impressive to me because of what they tell us about the function of the brain, but they're small on the scale of the moral judgments that we actually make.

Why? Because your brain is seeing that same information as if the right one is still under red light, and the left one is still under green light.

But I want to start with the easiest question and the question you really should have all asked yourselves at some point in your life, because it's a fundamental question if we want to understand brain function.

Your brain is learning. And it's learning that the right side of its visual field is under red illumination the left side of its visual field is under green illumination.

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

Call a user defined function given by the function parameter.

Function

That routine, rule based, left brain work certain kinds of accounting, certain kinds of financial analysis, certain kinds of computer programming has become fairly easy to outsource, fairly easy to automate.

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.

So what I'm showing you, from left to right, is how much activity there was in this brain region, and from top to bottom, how much blame people said that Grace deserved.
