Quizplus · Accepted Answer

The ventromedial nucleus is responsible for regulating satiety and reducing hunger. Damage to this area can cause overeating and weight gain, which matches Pedro's symptoms described in the scenario. The other brain regions listed (lateral hypothalamus, thalamus, and paraventricular nucleus) are also involved in regulating appetite and energy balance, but their specific functions do not match Pedro's symptoms as closely as the ventromedial nucleus.
