Imperial College Study (2012): How Psychedelic Work Can Increases Brain Connectivity and Reduce Rigid Thinking

A landmark 2012 study from Imperial College London, led by Robin Carhart-Harris, explored the effects of psilocybin, the active compound in magic mushrooms - on depression. Using brain imaging, the researchers discovered that psilocybin didn’t work by “stimulating” happiness, as many might assume, but rather by quieting the brain’s default mode network - the area linked to rigid thinking and rumination. This temporary loosening of overly fixed brain patterns allowed patients to break free from depressive loops and gain fresh perspectives. It was one of the first modern studies to show that psychedelics could offer profound therapeutic potential where traditional treatments had failed.
