Electrolytic lesions in a circumscribed area of the rostral midbrain of rats shortened the inhibitory period following ejaculation, thereby increasing the number of ejaculations achieved in 1-hour tests. These lesions also interrupted the dorsal norepinephrine bundle as reflected in a 63 percent reduction in telencephalic or cortical norepinephrine.
