How "magic mushrooms" expand the brain
A human brain on "magic mushrooms" appears much as it does when a person is dreaming, suggests a new study at Imperial College London.
Researchers scanned the brains of 15 people before and after they received a shot of psilocybin, the hallucinogenic component of magic mushrooms and found that when a person was under the influence, the regions of his brain associated with emotion and memory appeared to become more synchronized. That's similar to what occurs when a person is in dream sleep.
The scientists also discovered that under psilocybin there seemed to be more possible patterns of brain activity, which may expalin why people on mushrooms feel as if they've "expanded" their minds.
But the study also found that the parts of the brain linked to "high thinking," such as self-consciousness, were less coordinated under psilocybin.
