The activities of dopamine and gaba ergic neurons in the ventral tegmental area and the nucleus accumbens play critical roles 此外,腹側(cè)背蓋區(qū)和伏隔核等部位的-氨基丁酸及其它非多巴胺能神經(jīng)遞質(zhì)系統(tǒng)在阿片強(qiáng)化作用中也起到重要作用。
Neuronal cells containing nos have been found in basal forebrain , pedunculopontine tegmental nuclei , dorsal raphe nuclei , olfactory bulb and hippocampus which have been proved to participate in the regulation of sleep / waking cycle Nos在中樞神經(jīng)系統(tǒng)中分布廣泛,與睡眠有關(guān)的部位,如前腦基底部、腦橋背蓋、中縫背核、嗅球和海馬等均有較高密度的nos ,說明這些部位可以產(chǎn)生no 。
A large number of neurons with nig - li were seen in the anterior olfactory nuclei , accumbens nucleus , septal area , 09600045 , 39970377 , 39570109 ) 9 ventral pallidum , pallidum , caudate putamen , nucleus of the stria terminalis , anterior hypothalamic area , tuber cinereum area , lateral hypothalamic area , perifornical nucleus , supraoptic nucleus , arcuate nucleus , mammillar nuclei , substatia nigra , ventral tegmental area , retrorubral area , superior and inferior colliculus , periaqueductal gray , nucleus of the solitary tract , and superficial layers of the medullary and spinal dorsal horns 大量nk3受體樣免疫反應(yīng)陽性神經(jīng)元出現(xiàn)于前嗅核、伏隔核、隔區(qū)、腹側(cè)蒼白球、蒼白球、尾殼核、終紋床核、下丘腦前區(qū)、下丘腦結(jié)節(jié)區(qū)、下丘腦外側(cè)區(qū)、穹隆周區(qū)、視上核、弓狀核、乳頭體、黑質(zhì)、腹側(cè)被蓋區(qū)、紅核后區(qū)、上丘和下丘、導(dǎo)水管周圍灰質(zhì)、孤束核、及延髓和脊髓背角淺層。
In the present study , in order to investigate the effects of endogenous estrogen on the daergic terminals in amy and the daergic neurons in midbrain , fast cyclic voltammetry ( fcv ) was used to examine da release evoked by electrical stimulation from amy of female rats in different phases of estrus cycle , ovx rats and male rats . and tyrosine hydroxylase ( th ) immunohistochemi stry was employed to measure the numbers of daergic neurons of ventral tegmental area ( vta ) and substantia nigra ( snc ) in the rats 因此,為進(jìn)一步探討大鼠內(nèi)源性雌激素水平的變化對(duì)amyda能神經(jīng)系統(tǒng)及中腦da能神經(jīng)元的影響,本工作應(yīng)用快速周期伏安法( fcv )在體監(jiān)測(cè)了處于動(dòng)情周期各期雌鼠、 ovx鼠和雄鼠經(jīng)電刺激誘發(fā)的amyda釋放,并應(yīng)用酪氨酸羥化酶( th )免疫組化方法測(cè)定了以上各組大鼠腹側(cè)背蓋區(qū)( vta ) 、黑質(zhì)( snc )的th陽性神經(jīng)元數(shù)目。
