Scientists have for the first time scanned the brains of people using LSD and found the psychedelic drug frees the brain to become less compartmentalized and more like the mind of a baby.
A research team led by scientists at Imperial College London said that while normally the brain works on independent networks performing separate functions such as vision, movement and hearing, under LSD the separateness of these networks breaks down, leading to a more unified system.
"In many ways, the brain in the LSD state resembles the state our brains were in when we were infants: free and unconstrained," said Robin Cahart-Harris, who led the study. "This also makes sense when we consider the hyper-emotional and imaginative nature of an infant's mind."
