Estrogens and progestins alter electrical and chemical features of nerve cells, particularly in hypothalamus. Temporally, these events follow nuclear receptor occupation by these steroids, although not all effects have been proved to depend on translocation of receptors to the nucleus. Narrowing studies to focus on particular medial hypothalamic cells has been useful for understanding some of the actions of these steroids in brain. The variety of morphological, chemical, and electrical effects allow for a multiplicity in the cellular functions controlled by these hormones.
