 Since ascorbic acid (Vitamin C) enhances DA transmission in mesolimbic and nigrostriatal pathways, it has been shown that infusions of ascorbic acid into the mPOA increases appetitive behaviors compared to controls.In male rats, the mPOA affects the consummatory phase of sexual behavior, and possibly motivation, with lesions causing a complete loss of copulatory behaviors.Conversely, electrical stimulation of this area triggers male copulatory behavior, as measured by decreases in the latency to ejaculate.
