Its conclusions, predictions, and assertions represent the antithesis of what I once believed. Holograms encode messages carried by waves, waves of any sort, in theory. And holograms of all types share in common the fact that they encode information about a property of waves known as phase . I will defer definition of wave phase until later in the book. To reconstruct phase, which a hologram permits, is to regenerate a wave's relative shape and thus recreate any message or image the original wave communicated to the recording and storage medium.
Memory often survives massive brain damage, even the removal of an entire cerebral hemisphere.
In the 1920s the celebrated psychologist Karl Lashley, with whom Pribram once worked, demonstrated that the engram, or memory trace, cannot be isolated in any specific compartment of a rat's brain. For as unlikely as this may seem, the message exists, whole, at every point in the medium. My own research has not always focused directly on memory. Regeneration of tissues and organs held my fascination for many years, and I am still pursuing certain questions about the molecular aspects of the regrowth of muscle tissue. I had the persistent hunch that all recurrent biological events, developmental or neural, might be explained by one unified theory.
