Eight Circuits of the Brain by Timothy Leary (Edited by Matthew Clark)
This is a special edited version of psychedelic maverick Timothy Leary's Eight Circuits of the Brain theory - an explanation of both biological evolution and the development of the human nervous system. The theory appeared in several of Leary's publications in the 1970s and 1980s, and has been collated here in a handy form. An introduction by the editor, Matthew Clark, provides an account of how the theory originated and where it was first published.
This is a special collaboration between the Psychedelic Press and the charity Breaking Convention - profits from the sale of this publication go to BC to help promote and disseminate information about psychedelic research.
