Abstract
Increased dopamine (DA) in the medial preoptic area (MPOA) facilitates male sexual behavior. A major source of innervation to the MPOA is the medial amygdala (MeA). We now report that chemical stimulation of the MeA enhanced levels of extracellular MPOA DA in anesthetized male rats. These results suggest that DA activity in the MPOA can be regulated by input from the MeA to the MPOA.
摘要
内侧视前区（MPOA）中多巴胺（DA）水平升高会促进雄性性行为。对MPOA进行神经支配的一个主要来源是内侧杏仁核（MeA）。我们现在报告，在麻醉的雄性大鼠中，对MeA进行化学刺激会提高细胞外MPOA DA的水平。这些结果表明，MPOA中的DA活性可由从MeA到MPOA的输入进行调节。
