The Serotonin Hypothesis of Psychosis

This clip, from NEI's Stahl's Essential Videos, covers the serotonin hypothesis of psychosis. See more essentials of psychopharmacology from Dr. Stahl and NEI at https://nei.global/epvideos Although serotonin receptors and synapses are ubiquitous throughout the brain, the serotonin hyperfunction hypothesis of psychosis suggests that psychosis may be caused by an imbalance in excitatory 5HT2A receptor stimulation of those glutamate pyramidal neurons discussed above that directly innervate VTA/mesostriatal integrated hub dopamine neurons and visual cortex neurons. The hallucinogens LSD, mescaline, and psilocybin, which are all powerful 5HT2A agonists, have long been known to induce psychosis, dissociative experiences, and especially visual hallucinations by overstimulating prefrontal and visual cortex 5HT2A receptors. These symptoms can be blocked by 5HT2A antagonists, demonstrating that hallucinogens cause psychosis by 5HT2A stimulation. 🧠💡 Struggling to grasp complex psychopharmacologic concepts?
