Exempel på hur man kan använda PREOPTIC i en mening

• The nucleus accumbens (NAc or NAcc; also known as the accumbens nucleus, or formerly as the nucleus accumbens septi, Latin for 'nucleus adjacent to the septum') is a region in the basal forebrain rostral to the preoptic area of the hypothalamus.
• Between these two organs is the median preoptic nucleus, which has multiple nerve connections with the two organs, as well as with the supraoptic nuclei and blood pressure control centers in the medulla oblongata.
• The ventrolateral preoptic nucleus (VLPO), also known as the intermediate nucleus of the preoptic area (IPA), is a small cluster of neurons situated in the anterior hypothalamus, sitting just above and to the side of the optic chiasm in the brain of humans and other animals.
• MCH neurons are mainly concentrated in the lateral hypothalamic area, zona incerta, and the incerto-hypothalamic area, but they are also located, in much smaller amounts, in the paramedian pontine reticular formation (PPRF), medial preoptic area, laterodorsal tegmental nucleus, and the olfactory tubercle.
• In rats, central division of the medial preoptic nucleus (MPNc) is an important component of SDN-POA and evidence showed that the number of apoptotic cells within MPNc is greater in females than in males between postnatal day (PD) 7 and PD10.
• Also, the nucleus raphe pallidus receives afferents from the medial preoptic area, median preoptic nucleus and lateral paragigantocellular reticular nuclei.
• Dexmedetomidine induces sedation by decreasing activity of noradrenergic neurons in the locus ceruleus in the brain stem, thereby increasing the downstream activity of inhibitory γ-aminobutyric acid (GABA) neurons in the ventrolateral preoptic nucleus.
• The DMH sends information to the ventrolateral preoptic area, locus coeruleus, and orexinergic neurons in order to aid in the regulation of wakefulness.
• Forming a critical part of the anteroventral third ventricle and the midline of the lamina terminalis, the median preoptic nucleus occupies an anatomical position that allows it to play an important role in many aspects of homeostatic regulation.
• Increases in body and skin temperature are detected by visceral and peripheral thermoreceptors, which send signals via class C and Aδ-fiber afferent somatic neurons through the lateral spinothalamic tract to the preoptic nucleus of the hypothalamus for processing.
• Low-threshold calcium spikes have been described in neurons from a variety of brain nuclei, including the thalamic relay, medial pontine reticular formation, lateral habenula, septum, deep cerebellar nuclei, CA1-CA3 of the hippocampus, association cortex, paraventricular and preoptic nuclei of the hypothalamus, dorsal raphe, globus pallidus, striatum, and subthalamic nucleus.
• In Macaca fascicularis, these inputs include the amygdala (specifically the anterior amygdaloid area, the basolateral nucleus, and the periamygdaloid cortex), the medial septum and the diagonal band of Broca, the claustrum, the substantia innominata and the basal nucleus of Meynert, the thalamus (including the anterior nuclear complex, the laterodorsal nucleus, the paraventricular and parataenial nuclei, the nucleus reuniens, and the nucleus centralis medialis), the lateral preoptic and lateral hypothalamic areas, the supramammillary and retromammillary regions, the ventral tegmental area, the tegmental reticular fields, the raphe nuclei (the nucleus centralis superior and the dorsal raphe nucleus), the nucleus reticularis tegementi pontis, the periaqueductal gray, the dorsal tegmental nucleus, and the locus coeruleus.
• Increases in glucose concentration excite and induce vasodilation in ventrolateral preoptic nucleus neurons of the hypothalamus via astrocytic release of adenosine that is blocked by A2A receptor antagonists like caffeine.
• It used to be thought that pallium equals cortex and subpallium equals telencephalic nuclei, but it has turned out, according to comparative evidence provided by molecular markers, that the pallium develops both cortical structures (allocortex and isocortex) and pallial nuclei (claustroamygdaloid complex), whereas the subpallium develops striatal, pallidal, diagonal-innominate and preoptic nuclei, plus the corticoid structure of the olfactory tuberculum.
• The anteroventral periventricular nucleus (AVPV) is a small cluster of cells located in the preoptic area of hypothalamus of the brain that is abundant in nuclear hormone receptors in a sexually dimorphic manner, strongly implicated, in rat models, as being neonatally imprinted and subsequently controlling sex-typical physiology and behaviors.
• The mechanical stimulation of the ewe's vagina and cervix by expulsion of the fetus induces a neural release of oxytocin in the paraventricular nucleus of the hypothalamus, as well as in the bed nucleus of the stria terminalis, medial preoptic area and the olfactory bulb.
• Outputs from the parabrachial nucleus originate from specific subnuclei and target forebrain sites involved in autonomic regulation, including the lateral hypothalamic area, ventromedial, dorsomedial, and arcuate hypothalamic nuclei, the median and lateral preoptic nuclei, the substantia innominate, the ventroposterior parvicellular and intralaminar thalamic nuclei, the central nucleus of the amygdala, and the insular and infralimbic cortex.
• However, cholinergic neurons in the magnocellular preoptic nucleus and Substantia innominata have increased firing rates with fast cortical (gamma) Electroencephalography activity during wake and rapid eye movement sleep.
• However, he criticized LeVay for being unaware of some relevant research, and making a number of factual errors, such as that orgasm is caused by the neurotransmitter oxytocin, that female rats fail to display maternal behavior after hypophysectomy, that lesions of the ventromedial nucleus of the hypothalamus reduce presentational behavior displayed by female monkeys, that antiandrogenic drugs block the masculinization of the sexually dimorphic subdivision of the medial preoptic area in male rats, and that vaginal olfactory cues are the primary determinants of masculine sexual arousal in male primates.
• Anteromedial central arteries (also anteromedial perforating arteries, or anteromedial ganglionic arteries) are arteries that arise from the anterior cerebral artery and anterior communicating artery, and pass into the substance of the cerebral hemisphere through the (medial portion of) the anterior perforated substance to supply the optic chiasm, (anterior nucleus, preoptic area, and supraoptic nucleus of the) hypothalamus, lamina terminalis, septum pellucidum, (anterior portions of the) columns of fornix, rostrum of corpus callosum, (anterior portion of) putamen, head of caudate nucleus, and cingulate cortex.
