Mechanism of Action

When exploring the effects of psilocybin on the brain, understanding its mechanism of action is crucial. Psilocybin, the active compound in magic mushrooms, interacts with the brain in intricate ways, influencing serotonin receptors and altering brain dynamics. In this section, we delve into the specifics of how psilocybin affects serotonin receptors and induces changes in brain network connectivity.

Serotonin Receptors and Brain Dynamics

Psilocybin binds with high affinity to serotonin 5-HT2A receptors, which are densely located in areas of the brain responsible for mediating mood and anxiety disorders. This interaction with serotonin receptors is closely linked to the production of hallucinatory effects. A study conducted by Weill Cornell Medicine researchers discovered that psilocybin, along with LSD, reduces the energy required for the brain to transition between different activity states by activating serotonin receptors on brain cells [8].

The distribution of serotonin 2A receptors in the brain, the primary targets of psilocybin, is optimized to lower state transition energies. The heightened activity of these receptors by psilocybin leads to a substantial reduction in energy barriers for state transitions in the brain.

Brain Network Changes and Connectivity

Psilocybin induces significant disruptions in connectivity across cortical networks and subcortical structures, resulting in more than a three-fold increase in acute changes in functional networks compared to methylphenidate. These alterations manifest as desynchronization of brain activity across spatial scales, consistent with distortions of space-time and self-perception.

The acute effects of psilocybin on the brain are most pronounced in the default mode network (DMN), a brain network linked to the anterior hippocampus and associated with self-awareness. Psilocybin prompts a persistent decrease in functional connectivity between the anterior hippocampus and cortex, particularly the DMN. Although this connectivity reduction lasts for weeks, it tends to normalize after six months, offering insights into the pro-plasticity and anti-depressant effects of psilocybin.

Understanding how psilocybin interacts with serotonin receptors and alters brain connectivity provides valuable insights into the psychedelic effects of magic mushrooms and their potential therapeutic applications. Further research into these mechanisms may pave the way for innovative treatments in mental health and addiction therapy.
