Hypothalamus—the part of the brain mainly concerned with homeostasis
The Hypothalamus is a small part of the brain located just below the thalamus on both sides of the third ventricle. It sits just inside the two tracts of the optic nerve and just above the pituitary gland.
The hypothalamus is mainly concerned with homeostasis. It regulates things like hunger, thirst, response to pain, levels of pleasure, sexual satisfaction and anger. It also has a part to play in regulating pulse, blood pressure, breathing and arousal in response to emotional circumstances.
The hypothalamus’ function is internal monitoring. Being part of the brain that is associated with inward movement, it is looking at the internal spaces. Because it’s constantly keeping track of what’s going on inside the body, it is a key player in the weight-loss process.
The hypothalamus also regulates functions in the body through its connection to the pituitary. The pituitary pumps hormones into the bloodstream that are vitally important in regulating growth and metabolism.
