• He found that he could induce different types of responses when stimulating the anterior ( lateral ) hypothalamus compared to stimulating the posterior ventromedial hypothalamus.
• This experiment was to support the theory that damage to the hypothalamus, particularly the ventromedial hypothalamus, leads to obesity caused by the overconsumption of food.
