Arcuate Nucleus

The arcuate nucleus is a group of neurons located in the hypothalamus of the brain. It releases dopamine which travels to the pituitary gland where it controls the release of prolactin. The arcuate nucleus is also responsible for the release of neuropeptides that are involved in processes like feeding and sleep. It releases anorexigens like CART and neuropeptide Y which are involved in hunger and the feeling of satiation and fullness.
