One of the interesting findings is that the psychoactive chemicals seem to dampen the parts of the brain associated with executive function, what the Freudian model might think of as the ego. This likely results in the diminishing of personal identity and the expansion of worldcentric and cosmocentric consciousness.

This week, researchers from Imperial College London publish two separate studies of the effects of psilocybin, the psychoactive ingredient of magic mushrooms. The first appeared in Proceedings of the National Academy of Sciences on Monday, and I've written a news story about it for Nature. It's one of a small number of studies using brain scanning to examine the neurological effects of the drug. The second, published in the British Journal of Psychiatry, examines the effects of the drug on the quality of recalled memories.Read the whole article.
The past decade has seen a resurgence in psychedelic research, not least because psilocybin and other psychedelic drugs have potential therapeutic value for various psychiatric conditions. Here, I'd like to focus on another aspect of the new studies. Robin Carhart-Harris, lead author on both of the papers, interprets the findings within the framework of neuropsychoanalysis. I briefly describe this emerging movement, and how it might be used to explain the psychological effects of psilocybin.
