This Is Your Brain on Magic Mushrooms

The article "This Is Your Brain on Magic Mushrooms" describes network theory in mathematics being applied to data from fMRI studies on subjects taking psilocybin.

"The findings seem to explain some of the psychological experiences of a psilocybin trip. Linear thinking and planning become extremely difficult, but nonlinear “out of the box” thinking explodes in all directions. By the same token, it can become difficult to tell fantasy apart from reality during a psilocybin trip; but focusing on a certain thought or image — real or imagined — often greatly amplifies that thought’s intensity and vividness."
