This podcast episode explores the fascinating pharmacology of psilocybin and its transformation into psilocin in the brain. The discussion covers how psilocin interacts with the 5-HT2A receptor to influence mood, perception, and cognition. The hosts delve into the mechanisms behind neuroplasticity, including the role of BDNF and specific signaling pathways that contribute to potential therapeutic benefits for conditions like depression and anxiety. The conversation also examines how psilocybin affects brain networks, particularly its ability to quiet the default mode network while enhancing connectivity in other regions.
