Aggression, anger, and irritability emerge from dysregulated interactions between prefrontal and limbic circuits, with serotonin (5-HT) exerting a central regulatory influence. Among serotonergic targets, the 5-HT2A receptor has emerged as a key modulator of aggressive behavior. Convergent neuroimaging, postmortem, and preclinical studies consistently implicate heightened prefrontal 5-HT2A...
Clinical and laboratory findings suggest that cannabinoids and their receptors are implicated in schizophrenia. The role of cannabinoids in schizophrenia remains however poorly understood, as data are often contradictory. The primary aim of this study was to investigate whether the cannabinoid CB1 receptor antagonists rimonabant and AM251 are able to reverse deficits of sensorimotor gating...
