The suprachiasmatic nucleus (SCN) and the ventrolateral preoptic nucleus (VLPO) of the hypothalamus play crucial regulatory roles in mediating the effects of reproductive hormones on the sleep鈥搘ake cycle. Taken together, the work reviewed here reveals that the reproductive ho...
Melatonin: A hormone released primarily by the brain’s pineal gland that regulates the body’s sleep-wake cycle. Melatonin levels rise and fall naturally throughout the day, peaking in the evening (to promote feelings of sleepiness before bedtime) and dipping to their lowest levels in the morn...

parameters. The design of effective preventive and therapeutic strategies for women throughout their reproductive life depends greatly on our understanding of the mechanisms underlying hormonal modulation of the sleep-wake cycle.

In the aging male, there is a loss of overall efficiency and function of many body systems. These functions include changes in overall metabolism, strength, blood pressure, heart rate, appetite, body temperature, sleep/wake cycle, and sexual function. Perhaps the most essential organ system that...
After training, the level of dopamine decreases while the level of serotonin increases. Serotonin is a hormonal antagonist to dopamine and has various functions; amongst other things, it's involved in the regulation of thesleep-wake cycleand body temperature, it controls appetite and it lowers pai...
Sex hormones can drive appetite and behavior around food. In females, higher levels of estrogen tend to correlate with increased satiety, while increased progesterone levels maystimulate appetite. Since estrogen tends to elevate during the first half of the menstrual cycle in premenopausal women, longe...
These functional controls include: autonomic, endocrine, and motor function control. It is also involved in homeostasis and the regulation of both the sleep-wake cycle and in food and water intake. A number of important hormones are produced by the hypothalamus including: vasopressin (anti-diuretic...
