The activities of dopamine and gaba ergic neurons in the ventral tegmental area and the nucleus accumbens play critical roles 此外，腹侧背盖区和伏隔核等部位的-氨基丁酸及其它非多巴胺能神经递质系统在阿片强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在中枢神经系统中分布广泛，与睡眠有关的部位，如前脑基底部、脑桥背盖、中缝背核、嗅球和海马等均有较高密度的nos ，说明这些部位可以产生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受体样免疫反应阳性神经元出现于前嗅核、伏隔核、隔区、腹侧苍白球、苍白球、尾壳核、终纹床核、下丘脑前区、下丘脑结节区、下丘脑外侧区、穹隆周区、视上核、弓状核、乳头体、黑质、腹侧被盖区、红核后区、上丘和下丘、导水管周围灰质、孤束核、及延髓和脊髓背角浅层。

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，为进一步探讨大鼠内源性雌激素水平的变化对amyda能神经系统及中脑da能神经元的影响，本工作应用快速周期伏安法( fcv )在体监测了处于动情周期各期雌鼠、 ovx鼠和雄鼠经电刺激诱发的amyda释放，并应用酪氨酸羟化酶( th )免疫组化方法测定了以上各组大鼠腹侧背盖区( vta ) 、黑质( snc )的th阳性神经元数目。
