A collection of neurons (nerve cells) in the hypothalamus of the brain. Some arcuate neurons contain dopamine and act to inhibit the release of the hormone prolactin by the pituitary gland. Other arcuate neurons contain a substance called neuropeptide Y (NPY) and influence hunger. When activated, these neurons can produce remarkable increases in ea [..]

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 nu [..]
