Final answer:
Electrolytic lesions of the ventromedial hypothalamus impair sexual behavior, whereas electrical stimulation elicits repetitive bouts of copulation.
Step-by-step explanation:
Electrolytic lesions of the ventromedial hypothalamus impair sexual behavior whereas electrical stimulation elicits repetitive bouts of copulation. This has been observed in animal research, where lesions to the ventromedial hypothalamus completely disrupt a male rat's ability to engage in sexual behavior, while electrical stimulation of this area leads to repetitive bouts of copulation. Similarly, studies in animals have shown that limbic system structures like the amygdala and nucleus accumbens are involved in sexual motivation, with damage to these areas resulting in a decreased motivation to engage in sexual behavior.
