enki - I don't think it is a deviation, since AB has brought up his dissatisfaction with ideas about consciousness, and prefers his ideas about the soul.
Another area of research is into dementia, which is showing how our representations of the self, of others, of time, memory, and so on, can begin to disintegrate, via brain damage.
Another interesting area is to do with selective representation. For example, when an animal walks down a path, the amount of information coming in is huge - from the environment, its own body, and so on. And this applies to humans as well. Anyway, the idea of selective representation is that to avoid overload, the brain is able to construct 'naive' representations, which simplify reality for us. One example is colour.
This stuff seems very exciting to me, and I wonder what AB has to offer in return, in relation to the soul?
