Lub ventrolateral preoptic (VLPO) nucleus nyob rau hauv lub anterior hypothalamus yog qhov chaw loj ntawm lub hlwb uas tswj kev pw tsaug zog induction thiab tu. Nws cov neurotransmitter loj yog GABA, thiab thaum lub sijhawm tsaug zog, GABA tso tawm los ntawm VLPO nucleus yog inhibited los ntawm norepinephrine (NE) los ntawm locus ceruleus.
Lub ventrolateral preoptic ua li cas?
Lub ventrolateral preoptic nucleus (VLPO) yog ib pawg ntawm cov pw tsaug zog-active neurons uas tau txheeb xyuas nyob rau hauv lub hypothalamus ntawm nas thiab yog xav kom inhibit qhov loj ascending monoaminergic arousal systems thaum pw tsaug zog; VLPO ua rau insomnia.
Lub lateral preoptic nucleus ua dab tsi?
Lub cheeb tsam preoptic sab nraud (LPO) yog thaj tsam ntawm lub paj hlwb hypothalamic uas nws txoj haujlwm tsis tau tshawb nrhiav ntau. Feem ntau cov kev tshawb fawb tau tsom mus rau nws lub luag haujlwm hauv kev pw tsaug zog thiab nqhis dej (Osaka li al., 1993; Saad et al., 1996; Szymusiak et al., 2007). Qee qhov kev tshawb fawb me me qhia tias LPO koom nrog kev coj cwj pwm.
Dab tsi yog qhov preoptic nucleus secrete?
Lub nruab nrab preoptic nucleus yog bounded laterally by the lateral preoptic nucleus , and medially by the preopticperiventricular nucleus . Nws tso tawm gonadotropin-tso cov tshuaj hormones (GnRH), tswj kev sib koom ua ke ntawm cov txiv neej, thiab is loj dua rau txiv neej dua li poj niam.
Tuberomammillary nucleus ua dab tsi?
Lub tuberomammillary nucleus (TMN) ntawm hypothalamus yog tsuas yog qhov chaw ntawm lub hlwb histamine, thiab qhov chaw txhawb nqa kev txhawb nqa no dav dav. Hauv kev tshawb fawb tsiaj, histamine yog ib qho kev kawm zoo-txhawb cov tshuaj thaum xa mus rau BF, thaj chaw preoptic, TMN, lossis intraventricularly.
