Quizplus · Accepted Answer

The central pacemaker that controls circadian rhythms in many animals, including humans, is located in the suprachiasmatic nucleus (SCN) of the brain. This area is situated in the hypothalamus, directly above the optic chiasm, and it receives direct input from the eyes, allowing it to adjust the body's internal clock in response to light cues.
