Effects of 2-bromoterguride, a dopamine D2 receptor partial agonist, on cognitive dysfunction and social aversion in rats.

abstract：RATIONALE:Neuropeptide Y (NPY) is implicated in the pathophysiology of affective illness. Multiple receptor subtypes (Y1R, Y2R, and Y5R) have been suggested to contribute to NPY's effects on rodent anxiety and depression-related behaviors. OBJECTIVES:To further elucidate the role of Y1R in (1) NPY's anxiolytic-like ef...
