A research group at Imperial College London have made what major break through in understanding LSD’s impact on the brain. The first modern brain scans of people high on the drug have given researchers an unprecedented insight into the neural basis for effects produced by LSD. The scientists measured blood flow, functional connections within and between brain networks, and brainwaves in the volunteers on and off the drug.
The brain scans revealed that trippers experienced images through information drawn from many parts of their brains, and not just the visual cortex at the back of the head that normally processes visual information. Under the drug, regions once segregated spoke to one another.
Further images showed that other brain regions that usually form a network became more separated in a change that accompanied usersâ€™ feelings of oneness with the world, a loss of personal identity called â€œego dissolutionâ€.
There is more about the findings in the Guardian article: LSD’s impact on the brain revealed in groundbreaking images. More images and detailed information can be found in the original paper.
