Fairly interesting interview with Oliver Sacks. He's Professor of Neurology and Psychiatry at Columbia University Medical Center. He discusses his recet book about hallucinations. From the olfactory to the visual and audio....synthesasia, epilepsy, congenital blindness.
DMT gets a short mention. There is more talk about LSD. Worth a listen IMO
In his latest book Hallucinations, neurologist Oliver Sacks collects stories of individuals who can see, hear, and smell things that aren't really there -- such as strange voices, or collages of unrecognizable faces -- and explores the disorders and drugs that can produce such illusions.
http://www.sciencefriday...acks-hallucinations.htmlI am completely convinced that there is a wealth of information built into us, with miles of intuitive knowledge tucked away in the genetic material of every one of our cells. Something akin to a library containing uncountable reference volumes, but without any obvious route of entry. And, without some means of access, there is no way to even begin to guess at the extent and quality of what is there. The psychedelic drugs allow exploration of this interior world, and insights into its nature. - Shulgin
