preoptic area

The preoptic area is a region of the hypothalamus.

The anterior hypothalamic region is sometimes grouped with the preoptic area.

The second area that did not receive any virus from the prostate is the medial preoptic area.

Parallel pathways in the preoptic area are involved in regulation of body temperature and fever response.

Some differences are apparent even in gross neuroanatomy: most notable is the sexually dimorphic nucleus within the preoptic area.

Thermoregulation in both ectotherms and endotherms is controlled mainly by the preoptic area of the anterior hypothalamus.

The preoptic area contains thermosensitive neurons; these are important for TRH secretion.

Appetitive behaviors are also partly controlled by medial preoptic area as aromatase-knockout mice show deficits in sexual motivation.

Lesions of the rostral part of medial preoptic area also diminish preference for female by male rats.

The medial preoptic area of the brain is considered to control the expression of both male copulation and male appetitive sexual behavior.

However, appetitive behaviors are disrupted by the lesions in rostral part rather than caudal part of medial preoptic area.

Even more significantly, these cells had continued along their normal migratory path into the presumptive septal and preoptic areas, their normal target sites.

Approximately equal numbers of bladder and prostate neurons were found in all locations except for Barrington's nucleus and the medial preoptic area.

SWS is initiated in the preoptic area and consists of delta activity, high amplitude waves at less than 3.5 Hz.

The median preoptic nucleus is located dorsal to the other three nuclei of the preoptic area of the anterior hypothalamus.

Inhibitory influence from the brain is active at sleep onset, likely coming from the preoptic area (POA) of the hypothalamus.

The preoptic area is responsible for thermoregulation and receives nervous stimulation from thermoreceptors in the skin, mucous membranes, and hypothalamus itself.

Prenatal stress inhibits the masculinzation of the male brain by inhibiting the growth of the sexually dimorphic nucleus of the preoptic area.

The volume of SDN in medial preoptic area is modified by hormones, among which testosterone is proved to be of much importance.

Authors suggest this may cause the reduced in the sexually dimorphic nucleus of the preoptic area and says it is similar to the effects of neonatal castration.

These afferent neurons project up the spinal cord to the parabrachial area, which innervates several areas of the preoptic area, including the median preoptic nucleus.

Gonadotropins are released under the control of gonadotropin-releasing hormone (GnRH) from the arcuate nucleus and preoptic area of the hypothalamus.

It has been implied that the preoptic area is constantly inhibiting the raphe pallidus, especially the rostral portion, with GABA.

Evidence shows that SDN in medial preoptic area is not the prerequisite for the expression of male-typical sexual behaviour and sexual partner preferences in females.
