Any comments on the steroid allegations?

or cortical visual impairment.

Cortical Surface Reconstruction and Visualization

loss of cortical gray matter.

Cortical fluctuation. It could trigger a seizure.

He's got adrenal crisis. He's got Addison's disease. What?

It's all about cortical processing and forebrain specialization.

And the adrenal glands make androgens, which are a masculinizing hormone.

Females, like males, have in our bodies something called the adrenal glands.

The adrenal glands hemorrhage, the brain goes into shutdown, then the major organs.

But, no, even if we were all steroid filled football players, the answer is no.

What he had was an extreme form of a condition called congenital adrenal hyperplasia.

You can think about normal development as a loss of cortical mass,

Or maybe this is scarring from a cortical infection that we didn't...

Now this cortical folding presents a significant challenge for interpreting surface electrical impulses.

Now actually we've looked in several different cortical areas in the monkey learning this task.

Lee, I got a big problem, man! This boy's on a steroid he's got a light bear's punch Oh no!

There are 15 or 20 cortical areas that are changed specifically when you learn a simple skill like this.

So for example we can look to the cortical area that represents input that's controlling the posture of the monkey.

He had XX chromosomes, and in the womb, his adrenal glands were in such high gear that it created, essentially, a masculine hormonal environment.

We look in cortical areas that control specific movements, and the sequences of movements that are required in the behavior, and so forth.

In other words there is still a single, simple representation of the fingertips in this most organized of cortical areas of the surface of the skin of the body.

He got hospitalized and he would take this cocktail of pills every day, and one of those pills was a steroid which stunted his growth, and made him feel different from any of the other students.

That says to me, at least in rats and I think they have the same neurotransmitters that we do and a similar cortical architecture that play may be pretty important for our survival.

And it's important, if you try to model this, you can think about normal development as a loss of cortical mass, loss of cortical gray matter, and what's happening in schizophrenia is that you overshoot that mark, and at some point, when you overshoot, you cross a threshold, and it's that threshold where we say, this is a person who has this disease, because they have the behavioral symptoms of hallucinations and delusions.

This triggers the pituitary gland, a pea sized gland found at the base of the brain, to release adrenocorticotropic hormone which then stimulates the adrenal gland sitting on top of the kidneys to release cortisol, the major stress hormone.

And what was interesting was that in this one region, the 50 year old meditators had the same amount of cortex as the 25 year olds, suggesting that meditation practice may actually slow down or prevent the natural age related decline in cortical structure.

And if we take a slice of cortical tissue with one month of age and we simply look at those neurons, those are those black bodies that you see there, and the little processes that issue from them, they look like spiders, those are the dendrites that connect to other neurons.
