LSD is one of the most powerful drugs ever created, and for the first time ever, scientists at Imperial College London have successfully image scanned human brains that are under the influence of the psychedelic drug.
The study has had profound impacts on our understanding of consciousness. As one researcher explained, “Normally our brain consists of independent networks that perform separate specialised functions, such as vision, movement and hearing - as well as more complex things like attention. However, under LSD the separateness of these networks breaks down and instead you see a more integrated or unified brain. In many ways, the brain in the LSD state resembles the state our brains were in when we were infants: free and unconstrained.”
