hypothalamus

A structure in the diencephalon, above the midbrain. Its centers control emotion, hunger, and thirst, and it releases hormones that trigger the production of other hormones by the pituitary gland.

There are only two areas of the brain that are known to normally undergo ongoing large-scale neuronal replacement during adulthood on a cellular level -- so-called 'neurogenesis,' or the birth of new neurons -- the olfactory bulb and the subregion of the hippocampus called the dentate gyrus, with emerging evidence of lower level ongoing neurogenesis in the hypothalamus," said Jeffrey Macklis, Harvard University professor of stem cell and regenerative biology and HMS professor of neurology at Massachusetts General Hospital, and one of three corresponding authors on the paper.
