观察结果表明：在弓状核内有暗细胞和亮细胞两种神经元，它们可能兼具产生多巴胺和释放激素的功能。
The observations showed that there are two kinds of neurons (dark and light) in the arcuate nucleus which might be responsible for producing both dopamine and releasing hormones.
而微量注射甘氨酸则使膈神经放电显著减少和使弓状核诱发电位P2及N2波幅显著增大。
Phrenic nerve discharges were decreased and the amplitude of P2 and N2 waves of arcuatus nucleus evoked potentials were increased by microinjection of glycine into VLNTS.
结论：岩大神经管裂孔、弓状隆起等颞骨岩部结构是定位内耳道的重要标志。
Conclusion: The hiatus of canal for greater petrosal nerve and arcuate eminence are important landmarks to defined internal auditory canal.
在弓状核、视前内侧束内有密集的NOS阳性神经纤维。
The density of NOS positive fibers also could be seen in the arcuate nucleus and medial forebrain bundle.
方法：采用光、电镜技术和体视学方法对40只SD大鼠弓状核神经元的昼夜节律变化进行了形态定量研究。
Mehods: A morphometric study was made in 40 SD rats by light and electron microscopic technique, as well as stereological method.
同时发现室旁核、室周核、室周弓状核及视前大细胞核的VP阳性神经元有突起伸入到第三脑室室管膜或突出于脑室腔，视上核的VP阳性神经元也有突起投射至脑基底神经胶质板上或伸至蛛网膜下腔。
The process of VP-like cells in PVN, PN, AN and POM projected towards the third ventricle, and the process in SON towards the glial lamina in the basal surface of the brain or subdural space.
