Question

Dr. Pollini is investigating how the brain regulates patterns of eating behavior. He performs an experiment and finds that lesioning a particular brain region interferes with rodent’s ability to feel satiated. This, in turn, leads them to significantly increase their food intake and to gain weight. What area of the brain has Dr. Pollini lesioned?

Answer 1

The ventromedial hypothalamus

Step-by-step explanation:

The ventromedial hypothalamus, also called ventromedial nucleus, is a small part of the hypothalamus in the brain, which is responsible for the recognition of the feeling of fullness after eating, and gives the feeling of satiety at the brain level. Damage of the ventromedial hypothalamus would result in uncontrollable eating, as the ability to feel satiated is impaired.

We can conclude that Dr. Pollini lesioned the ventromedial hypothalamus, which led to the significant increase in their food intake.

Answer 2

ventromedial hypothalamus. It is responsible for terminating hunger, fear, thermoregulation, and sexual activity." This nuclear region is involved with the recognition of the feeling of fullness.
