What Psilocybin Does to Your Brain | The Neuroscience Explained

Psilocybin—the psychoactive compound found in “magic mushrooms”—has fascinated scientists for decades. But what actually happens inside the brain when someone takes it? In this video, we explore the neuroscience of psilocybin and how it alters brain activity, perception, and consciousness. Researchers have discovered that psilocybin can temporarily reorganize communication between different brain networks, including the default mode network, which is involved in self-reflection and our sense of identity. These changes may explain the profound experiences people report during psychedelic states. Recent clinical studies are also investigating psilocybin’s potential role in treating conditions such as depression, anxiety, and addiction. Scientists are now using modern brain imaging tools to better understand how this compound affects neural connectivity and cognition. In this episode, we break down the science behind psilocybin, how it interacts with serotonin receptors, and what brain scans reveal about the psychedelic experience.
