Abstract: An encyclopedia entry for "circadian rhythms" is presented. They refer to a biologic pacemaker which regulates physiologic fluctuation based upon a near 24-hour time period. They are found in all organisms, with the most potential stimulus being light. The suprachiasmatic nucleus in the hypothalamus of the brain serves as the master circadian rhythm clock which regulates human behaviors.
