Clinical and preclinical studies increasingly support the antidepressant potential of several anesthetic agents, including ketamine, propofol, nitrous oxide (N2O), sevoflurane, and isoflurane. Their therapeutic effects appear to arise from the regulation of multiple interconnected systems: modulation of glutamatergic and GABAergic signaling, interaction with monoaminergic neurotransmitters...
Dreaming is often reported by patients who undergo propofol-based sedation, but there have not been any studies to date focused on the incidence of dreaming and factors associated therewith following the administration of ciprofol anesthesia in patients undergoing painless gastroscopy. The present study was thus developed with the goal of assessing the incidence of dreaming. In total, this...
Posttraumatic stress disorder (PTSD) and depression are highly comorbid. Psilocybin exerts substantial therapeutic effects on depression by promoting neuroplasticity. Fear extinction is a key process in the mechanism of first-line exposure-based therapies for PTSD. We hypothesized that psilocybin would facilitate fear extinction by promoting hippocampal neuroplasticity. First, we assessed the...
