Our body’s master clock is located in a part of the brain’s hypothalamus called the suprachiasmatic nucleus, which receives light information from the retina in the eye and sends the information to other parts of the brain, including the gland that releases the sleep-signaling hormone melatonin...
(Figure 2). The hypothalamus controls many important body functions, such as sleep, blood pressure, temperature, hunger, thirst, and energy consumption and storage. Much like a computer microprocessor, the hypothalamus runs an algorithm that computes the information by following a set of rules. ...
