Question

Quizplus · Accepted Answer

The ventromedial hypothalamus plays a critical role in satiety. When it is lesioned, the rat loses the ability to recognize when it is full, leading to overeating. The parabiotic partner, sharing a circulatory system but with an intact ventromedial hypothalamus, will experience the opposite effect due to the shared circulation of satiety signals or metabolic consequences, leading to under-eating.
