We still have much to learn about the brain (let alone the mind); even though by now all sections of the brain have been probed down to the molecular level, no trace or imprint of a thought has ever been found within its tissue. As an analogy, the innate knowledge of probabilities that Seth postulates here may be related to the brain in the same way that memory evidently “happens” throughout its parts, instead of being localized in just one of them.

For material on mental and psychic expansions in old age, and the hemispheres of the brain, see the 650th session in Chapter 13 of Personal Reality.

[...]

[...] Portions of the brain not used lie latent, waiting for the recognition that will trigger them into activity (intently). When this happens, the mind will become aware of the rich bed of probabilities upon which the ego now rides so blindly.
