Abstract Psilocybin and other serotonergic psychedelics have re-emerged as therapeutics for neuropsychiatric disorders, including addiction. Psilocybin induces long-lasting effects on behavior, likely due to its profound ability to alter consciousness and augment neural connectivity and plasticity. Impaired synaptic plasticity in obesity contributes to ‘addictive-like’ behaviors, including...
Prefrontal serotonin 2A receptors (5-HT2A Rs) have been linked to the pathogenesis and treatment of schizophrenia. Many antipsychotics fully occupy 5-HT2A R at clinical relevant doses, and activation of 5-HT2A receptors by lysergic acid diethylamide (LSD) and LSD-like drugs induces a schizophrenia-like psychosis in humans. Subchronic phencyclidine (PCP) administration is a well-established...
