In what part of the brain can you find neurons that are responsible for satiety and cessation of eating at the end of a meal?

The neurons responsible for satiety and the cessation of eating are primarily located in the hypothalamus, specifically in the arcuate nucleus and the ventromedial hypothalamus (VMH).

1. Arcuate Nucleus: This area contains neurons that are sensitive to hormonal signals related to food intake and energy balance. It plays a critical role in regulating appetite by integrating signals from the rest of the body regarding hunger and satiety.

2. Ventromedial Hypothalamus (VMH): The VMH is often referred to as the "satiety center" of the brain. When activated, it promotes feelings of fullness and reduces food intake. Disruption to this area can lead to overeating and obesity due to a lack of satiety signals.

The hypothalamus acts as a crucial hub for the regulation of food intake, and its proper functioning is essential in maintaining energy homeostasis. In essence, the hypothalamus, through its various nuclei, coordinates hormonal and neural signals to ensure the body knows when it has had enough to eat.
