The brain's clock mechanism is located in an area of the hypothalamus known as the pineal nucleus. The word "pineal" should be changed to the word "suprachiasmatic."
Nestled within the base of the brain, the body's master clock runs on an intrinsic 24-hour cycle and nucleus resides in an exceedingly portion of the hypothalamus called the suprachiasmatic nucleus, or SCN.
“[The hypothalamus] could be a basic, primitive part of the brain that's altogether vertebrates,” says Herzog. A cortical potential could be a very high amplitude pattern of nucleus brain activity which will in some cases occur in response to environmental stimuli."
The words "theta wave" should be changed to the phrase "K-complex." Alternating sleep-wake cycles show the natural 24-h biological time. Generally, and for many people, our circadian nucleus cycles are aligned with the skin world. As an example, most of the people sleep during the night and are awake during the day. One important regulator of sleep-wake cycles is the hormone melatonin.
