In what way does eating increase after damage in and around the ventromedial hypothalamus? After damage to the paraventricular nucleus?
Expert Solution
Step 1 Introduction:
The ventromedial hypothalamus (VMH) is identified as the satiety center and indicates when a person has had enough amounts of food. Brain lesions that occur in this part result in obesity due to hyperphagia or excessive eating since the brain does not signal feelings of fullness after eating.
Similarly, lesions on the periventricular nucleus increase food intake and show higher levels of weight gain which is related to the accumulation of neuropeptide Y (it stimulates food intake).
