- The chemical "psilocybin"' found in magic mushrooms could be used to treat depression
- Psilocybin causes the introspective region of our brain to become less active

"Only by losing the self, can you find the self," explains Dr Robin Carhart-Harris, from Imperial College London. These may not be the usual words of a scientist but there is biology behind them. "People try and run away from things and to forget, but with psychedelic drugs they're forced to confront and really look at themselves," he says.
The drugs Carhart-Harris is referring to are hallucinogens such as magic mushrooms -- specifically the active chemical inside them, psilocybin. "We're beginning to identify the biological basis of the reported mind expansion associated with psychedelic drugs," he says. Psilocybin is not addictive and is interesting to researchers for its ability to make users see the world differently. The team at Imperial College has begun to unravel why.
Carhart-Harris scanned the brains of 30 healthy volunteers
after they had been injected with psilocybin and found the more primitive regions of the brain associated with emotional thinking became more active and the brain's "default mode network," associated with high-level thinking, self-consciousness and introspection, was disjointed and less active.
"We know that a number of mental illnesses, such as OCD and depression, are asso
