anterior hypothalamus

The anterior hypothalamus plays a role in regulating sleep.

When a receptor within the body senses a stressor, a signal is sent to the anterior hypothalamus.

According to the MeSH classification, it is considered part of the anterior hypothalamus.

The inner-cannula used for microinjections extended 3.0 mm beyond the guide to reach the anterior hypothalamus.

In mammals, such endogenous rhythms are generated by the suprachiasmatic nuclei of the anterior hypothalamus.

A fever occurs when the core temperature is set higher, through the action of the pre-optic region of the anterior hypothalamus.

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

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

In mammals, the linear decapeptide end-product is synthesized from a 92-amino acid pre prohormone in the preoptic anterior hypothalamus.

After the anterior hypothalamus receives the signal, corticotrophin-releasing factor (CRF) acts on the anterior pituitary.

Thus, sleep onset seems to arise from activation of the anterior hypothalamus along with inhibition of the posterior regions and the central midbrain tegmentum.

The pre-optic anterior hypothalamus has been shown to contain warm sensitive, cool sensitive, and temperature insensitive neurons, to determine the body's temperature setpoint.

Later, the brains were sliced on a vibratome and the sections were stained with thionin to confirm the location of the microinjection sites in the anterior hypothalamus.

INAH3 is the short form for the third interstitial nucleus of the anterior hypothalamus, and is the sexually dimorphic nucleus of humanes.

Bogaert's hypothesis argues that "the target of the immune response may be malespecific molecules on the surface of male fetal brain cells (e.g.,including those in the anterior hypothalamus).

Additionally, (not shown in diagram), the basal nucleus provides GABA-ergic inhibitory input to the pre-optic anterior hypothalamus (PAH).

POAH is an acronym for preoptic anterior hypothalamus, the part of the brain that senses core body temperature and regulates it to about 36.8 C (98.6 F).

The anterior hypothalamus is involved in processing reproductive functions and recent evidence suggests it helps integrate hormonal and sensory cues involved in sexual behavior and sexual preference.

He focused on a particular segment of the hypothalamus known as the third interstitial nucleus of the anterior hypothalamus, which previous studies had shown to differ significantly between men and women.

Male rats that are exposed to testosterone blockers during fetal development will emerge from the womb with characteristically feminine brains, including in the region that corresponds to the anterior hypothalamus in humans.

Background In golden hamsters, microinjections of arginine vasopressin (AVP) into the anterior hypothalamus trigger grooming and flank marking, a stereotyped scent marking behavior [ 1 2 ] .

In golden hamsters, the elevation of serotonin in the anterior hypothalamus following fluoxetine treatment can inhibit the activity of the AVP system related to aggressive behavior [ 10 11 ] .

Some light was thrown on the mechanisms on sleep onset by the discovery that lesions in the preoptic area and anterior hypothalamus lead to insomnia while those in the posterior hypothalamus lead to sleepiness.

Its presence in many animals has been widely studied and the importance of the vomeronasal system to the role of reproduction and social behavior (through influence on anterior hypothalamus) has been shown in many studies.
