When we come to research, if we want to find out the cause of autism, we're going to have to be much more specific, and that's why when it comes to research, I'm fairly strict with respect to criteria. When it comes to treatment, I'm much more open to not making that differentiation.

Not only when one does meditation one is getting into a different realm, cognitively, but if you look at the imaging that's done on people when they're meditating, they indeed are entering a different portion of the brain which is activated.

I have a fairly strict definition of early infantile autism. That is not to say that people who don't meet that classic description don't have autism, but we might do well to narrow our definitions, and our samples, down to groups that are very similar, because I think you're more likely to find the cause.

Now I realize, and I acknowledge, that the right brain/left brain distinction is a tremendous oversimplification. We don't come neatly divided into right and left hemispheres, but the fact is that the two hemispheres of the brain do specialize in certain functions.

Not everyone who has a savant skill I would equate with a genius.

To some extent, we all have quirks or idiosyncrasies, and some geniuses, because of how bright they are and how focused they are, may have liberal eccentricities, but they're not at a disabling level.

Savant syndrome, characteristically, consists of left hemisphere dysfunction coupled with right hemisphere emergence, and what you see in the savant are basically right brain skills.

There is such a thing as genius, and these are people who do not have a formal disability, DSM-IV-type. They may have liberal eccentricities or quirks in their personality, but they don't rise to the level of a disability.

With respect to why some acquired savants are musical, and some are good at the arts, and some are mathematical, why aren't they all the same I think that has to do with this genetic endowment that all of us have.

Savant syndrome and autism, I think, are not disorders of brain structure, but they're disorders of brain function.

The narrower we define autism, and the more strictly we control for particular behaviors, the more likely we are to find what I think are the subgroups of autism.

We have medicalized a lot of things that I think are not really medical conditions.
