Simplified control circuit of human thermoregulation. [8] The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus ...
The anterior hypothalamic nucleus is a nucleus of the hypothalamus. Its function is thermoregulation (cooling) of the body. Damage or destruction of this nucleus causes hyperthermia. The anterior hypothalamus plays a role in regulating sleep. [1] The anterior hypothalamic region is sometimes grouped with the preoptic area. [2]
The hypothalamus is highly involved in maintaining homeostasis of the body, and the median preoptic nucleus is no exception, contributing to regulation of blood composition, body temperature, and non-REM sleep. The median preoptic nucleus is highly involved in three main areas. These include osmoregulation, thermoregulation, and sleep ...
The median preoptic nucleus is located along the midline in a position significantly dorsal to the other three preoptic nuclei, at least in the crab-eating macaque brain. It wraps around the top (dorsal), front, and bottom (ventral) surfaces of the anterior commissure.
Neurons from the pre-optic and hypothalamic regions of the brain that respond to small changes in temperature have also been described, providing information on core temperature. The hypothalamus is involved in thermoregulation , the thermoreceptors allowing feed-forward responses to a predicted change in core body temperature in response to ...

The posterior nucleus of the hypothalamus is one of the many nuclei that make up the hypothalamic region of the brain. Its functions include elevation of blood pressure, pupillary dilation, and shivering or body heat conservation (thermoregulation). [1] Damage or destruction of this nucleus causes hypothermia.
The ventromedial nucleus of the hypothalamus (VMN, VMH or ventromedial hypothalamus) is a nucleus of the hypothalamus. In 2007, Kurrasch et al . found that the ventromedial hypothalamus is a distinct morphological nucleus involved in terminating hunger, fear, thermoregulation, and sexual activity. [ 1 ]
