Inspired by McKenna & Sheldrake, I enjoy the model of the nervous system tuning in intelligence via morphic resonance. I don't know that I "believe" in it, but it jives well with some of my weirder experiences.

A friend used to work for an academic publisher and got me a copy of "World Futures - The Journal of General Evolution" edited by Ervin Laszlo, a special issue all about the Akashic Field. (or A-Field when feigning respectability!) Lot of neat ideas out there for memory and intelligence existing independent of human brains.

There's also that great bit from "The Invisible Landscape" about Karl Lashley's experiments with rats where only total removal of the cerebrum was sufficient to totally disrupt recall, suggesting holographic memory storage :)))
