About this episode

The episode discusses how activation of intracellular serotonin 2A receptors contributes to the effects of psychedelics on brain plasticity and antidepressant-like properties.

TWiN explains the finding that activation of intracellular, not plasma membrane, serotonin 2A receptors is responsible for the plasticity-promoting and antidepressant-like properties of psychedelic compounds.
