Increasing evidence suggests an important role of 5-HT, and 5-HT2A receptors in particular, in the etiology and treatment of schizophrenia. The prepulse inhibition paradigm is used as a model for sensorimotor gating processes that are disrupted in schizophrenia. The present study used the selective serotonin2A (5-HT2A) antagonist and putative antipsychotic agent MDL 100,907 to evaluate the...
Increasing evidence suggests an important role for serotonin (5-HT) neurons in the etiology and treatment of schizophrenia. The prepulse inhibition paradigm is used as a model for sensorimotor gating processes that are disrupted in schizophrenia. The present study assessed the general role of 5-HT in modulating auditory and visual prepulse inhibition in Wistar rats. A general overactivation of...
