While I haven't read the book, I have read some stuff about Bohm and Pribram. As I understood their reasoning, Bohm started with the fact that if you take a holographic negative and chop it into pieces, you can get (with various degrees of degradation) the whole image back. He argues that holograms are wave interference patterns and this each part contains the whole, and appears to operate at quantum and macro levels. The only way he sees this is as possible is if what we call "reality" is no more than a three dimensional hologram formed by wave interference patterns.
Pribram argues from neurophysics, using the fact that even in people who have had parts of the brain removed, memories (or at least parts of them) are recoverable. I believe his opinion is that the mind is a complex of quantum interferences patterns and that make some of what i currently called parascience explainable.
After that it gets really weird. And so far it remains highly speculative (or did up to two years ago)
