Effects of Psilocybin & Other Selective Serotonin Agonists on Hippocampal-Dependent Learning & Neurogenesis

Neurogenesis in the hippocampus provides a biological substrate for studying the cognitive effects of psychedelic substances. Serotonin 5-HT2A agonists, such as psilocybin, potentially influence the formation of new neurons and the subsequent maturation of hippocampal circuitry, which is linked to improvements in learning and problem-solving abilities. Classical conditioning models in rodents serve as a mechanism to explore how these substances impact brain plasticity. By examining how serotonin receptor agonists modulate the birth of new neurons in the dentate gyrus, researchers gain insight into how these compounds might offer therapeutic applications for conditions involving impaired neurogenesis.
