A team of researchers form the UT Southwestern Medical Center and University of Tsukuba have identified key cells within the brain that are critical for determining circadian rhythms, the 24-hour processes that control sleep and wake cycles, as well as other important body functions such as hormone production, metabolism, and blood pressure.  Circadian rhythms are generated by the suprachiasmatic nucleus (SCN) located within the hypothalamus … Continue reading Researchers identify elusive cell type in the brain that control circadian rhythms.
