So for the first time we've actually been able to record from neurons in the fly's brain while the fly is performing sophisticated behaviors such as flight.

But this is just one of many neuromodulators that's in the fly's brain.

So I really think that, as we learn more, it's going to turn out that the whole fly brain is just like a large version of this stomatogastric ganglion, and that's one of the reasons why it can do so much with so few neurons.

So a typical cell, like the neurons in our brain, has a region called the dendrites that receives input, and that input sums together and will produce action potentials that run down the axon and then activate all the output regions of the neuron.

The reptilian part of our brain, which sits in the center of our brain, when it's threatened, it shuts down everything else, it shuts down the prefrontal cortex, the parts which learn, it shuts all of that down.

And more interesting, however, is the brain in this child was still growing.

At age three, if you have a still-growing brain, it's a human behavior.

In chimps, by age three, the brain is formed over 90 percent.

So, the still-growing brain in this individual tells us that childhood, which requires an incredible social organization, a very complex social organization, emerged over three million years ago.

This view is conditioned by the fact that many of the drugs that are prescribed to treat these disorders, like Prozac, act by globally changing brain chemistry, as if the brain were indeed a bag of chemical soup.

When we think about cognition, we analogize the brain to a computer.

It's just that they don't bathe the brain like soup.

Rather, they're released in very specific locations and they act on specific synapses to change the flow of information in the brain.

So if we ever really want to understand the biological basis of psychiatric disorders, we need to pinpoint these locations in the brain where these chemicals act.

Now to begin to overcome our ignorance of the role of brain chemistry in brain circuitry, it's helpful to work on what we biologists call "model organisms," animals like fruit flies and laboratory mice, in which we can apply powerful genetic techniques to molecularly identify and pinpoint specific classes of neurons, as you heard about in Allan Jones's talk this morning.

Dopamine plays a number of important functions in the brain, including in attention, arousal, reward, and disorders of the dopamine system have been linked to a number of mental disorders including drug abuse, Parkinson's disease, and ADHD.

We take our dopamine receptor mutant flies and we genetically restore, or cure, the dopamine receptor by putting a good copy of the dopamine receptor gene back into the fly brain.

What that tells us is that dopamine is not bathing the brain of these flies like soup.

Rather, it's acting to control two different functions on two different circuits, so the reason there are two things wrong with our dopamine receptor flies is that the same receptor is controlling two different functions in two different regions of the brain.

So these results make me and my colleagues more convinced than ever that the brain is not a bag of chemical soup, and it's a mistake to try to treat complex psychiatric disorders just by changing the flavor of the soup.

What we need to do is to use our ingenuity and our scientific knowledge to try to design a new generation of treatments that are targeted to specific neurons and specific regions of the brain that are affected in particular psychiatric disorders.

You can't delete this data from your brain, but you can delete the cliched image of supplicant, impoverished peoples not taking control of their own lives.

He got thrown in jail for it, but I have his words tattooed on my brain.

You probably know, if you've been paying attention to some of the science literature that you can now take a skin cell and encourage it to become a liver cell or a heart cell or a kidney cell or a brain cell for any of us.

I'm going to talk about the strategizing brain.

I'm using my brain theory to see.

Where are these things happening in the brain?

So what you see here is a subtraction of areas in which there's more brain activity when you're playing people compared to playing the computer.

So we classify people by what they picked, and then we look at the difference between playing humans versus playing computers, which brain areas are differentially active.

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