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...

Sleep-wake cycle and the body clock Damage to the hypothalamus or the hypothalamic function, whether congenital or acquired, may cause significant health issues. What are the causes of hypothalamic dysfunction? There are several causes of hypothalamic dysfunction, which include: Surgery Head injury Tum...
as fear and rage, and in sexual behaviors. Despite its numerous vital functions, the hypothalamus in humans accounts for only 1-300 of total brain weight, and is about the size of an almond. Structurally, it is joined to thethalamus; the two work together to monitor the sleep-wake cycle...
Regulation of sleep-wake cyclesHelps regulate sleep along with other brain regionsThe suprachiasmatic nucleus sets timing of sleep cycle in response to daylight and darkness, using the visual pathways Initiation of physical responses to emotionsWithin the limbic system, contains nuclei for perceiving plea...
Interestingly, the activity of wake-promoting orexin neurons in the lateral hypothalamus (LH), a brain area involved in sleep/wake cycle control, increases during wakefulness, and decreases during sleep. While exploratory in vitro studies showed the excitatory effect of lactate on orexinergic activity...
of day. The suprachiasmatic nucleus maintains this sense of time and sends outputs to various regions of the brain to control activity levels, alertness, drowsiness, hunger, and body temperature. The end result of these outputs is the development of a sleep/wake cycle that remains fairly ...
The hypothalamus plays a key role in regulation of endocrine (pituitary function), metabolic (food intake, energy balance, and water metabolism), and nonendocrine (body temperature, sleep/wake cycle) functions. Diseases involving the hypothalamus give rise to variable associations of endocrine, metabol...

The lateral portion of the posterior hypothalamus contains several groups of neurons that have a major role in the regulation of the sleep–wake cycle (Saper and Fuller, 2017; Scammell et al., 2017). They include not only a subgroup of orexin/hypocretin neurons that maintain arousal and ...
