(Wired) This is what the human brain looks like when it is under the influence of LSD, researchers at Imperial College London have revealed.
In a study, published in Proceedings of the National Academy of Sciences (PNAS), the medical scientists revealed what happens in the brain when people have LSD-induced hallucinations. Scans showed volunteers' brains lighting up with activity after taking LSD; usually only the visual cortex at the rear of the brain is involved with image processing.
Dr Robin Carhart-Harris who led the research suggested that the volunteers were "seeing with their eyes shut" while hallucinating on LSD. "We saw that many more areas of the brain than normal were contributing to visual processing under LSD – even though the volunteers' eyes were closed. Furthermore, the size of this effect correlated with volunteers' ratings of complex, dreamlike visions."
