People who have taken psilocybin, the compound primarily responsible for the psychedelic effects of certain mushrooms, display a similar pattern of brain activity as seen during dreams when imaged by functional MRI, according to a researchers from Imperial College London.

The study, published in Human Brain Mapping, found that under psilocybin, activity in the brain network linked to emotional thinking—including the hippocampus and anterior cingulate cortex—became more pronounced, while activity in regions linked to high-level thinking and self-consciousness became more uncoordinated.
