The hypothalamus is a small but powerful brain region located deep within the brain. It plays a crucial role in regulating hunger and thirst, as well as other important bodily functions.
The amygdala is another brain region involved in emotion processing. While it doesn't directly control hunger and thirst, it can influence our emotional responses to food and water.
The medulla oblongata is part of the brainstem and helps regulate basic survival functions such as breathing, heart rate, and swallowing. It also plays a role in controlling hunger and thirst signals.
