preoptic area การใช้

• SFO neurons have also been experimentally shown to broadcast median preoptic area.
• In fact, SFO neurons have been experimentally shown to broadcast median preoptic area.
• The majority of sleep neurons are located in the ventrolateral preoptic area ( vlPOA ).
• Lesions of the rostral part of medial preoptic area also diminish preference for female by male rats.
• Neurotransmitters of the arousal system, such as acetylcholine and norepinephrine, work to inhibit the ventrolateral preoptic area.
• One example is the ventrolateral preoptic area, which release GABA reuptake inhibitors, which interrupt wakefulness and arousal.
• Appetitive behaviors are also partly controlled by medial preoptic area as aromatase-knockout mice show deficits in sexual motivation.
• However, appetitive behaviors are disrupted by the lesions in rostral part rather than caudal part of medial preoptic area.
• SWS is initiated in the preoptic area and consists of delta activity, high amplitude waves at less than 3.5 Hz.
• PGE2 acts on neurons in the preoptic area ( POA ) through the prostaglandin E receptor 3 ( EP3 ).
• Some differences are apparent even in gross neuroanatomy : most notable is the sexually dimorphic nucleus within the preoptic area.
• It has been implied that the preoptic area is constantly inhibiting the raphe pallidus, especially the rostral portion, with GABA.
• Also, the nucleus raphe pallidus receives afferents from the medial preoptic area, median preoptic nucleus and lateral paragigantocellular reticular nuclei.
• The volume of SDN in medial preoptic area is modified by hormones, among which testosterone is proved to be of much importance.
• Gonadotropins are released under the control of gonadotropin-releasing hormone ( GnRH ) from the arcuate nucleus and preoptic area of the hypothalamus.
• The medial preoptic area of the brain is considered to control the expression of both male copulation and male appetitive sexual behavior.
• The DMH sends information to the ventrolateral preoptic area, locus coeruleus, and orexin neurons in order to aid in the regulation of wakefulness.
• 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.
• The sleep neurons in the preoptic area receive inhibitory inputs from some of the same regions they inhibit, including the tubermammillary nucleus, raphe nuclei, and locus coeruleus.
• This area is normally inhibited by signals from the heat center in the anterior hypothalamic-preoptic area but is excited by cold signals from the skin and spinal cord.
