Andrew Schally studied how the hypothalamus controls secretion by the pituitary gland through small peptides. His work helped establish a chemical connection between brain activity and the release of hormones, and he shared the 1977 Nobel Prize in Physiology or Medicine for discoveries concerning brain peptide hormone production. He worked at Tulane and the Veterans Affairs hospital in New Orleans for more than four decades.[ref]

One important experimental question was whether separate hypothalamic signals were needed for the two gonadotropins, luteinizing hormone and follicle-stimulating hormone. Schally and colleagues' 1971 report described a purified hypothalamic factor that stimulated both. This connected a chemically characterized signal to two measured pituitary gland responses and helped establish the role of gonadotropin-releasing hormone.[ref]
