1.Efferents from the optic tectum to the brain stem in the Japanese quail were studied with the anterogradely biocytin method. After injection of biocytin into the ipsilaterl optic tectum, labeled terminals were seen in the rotund nucleus, neuropil part of the ventral lateral geniculate nucleus, principal part of the dorsal lateral geniculate nucleus, lateral part of the dorsolateral thalamic nucleus, central gray matter. The present results suggest that tectofugal impulses in the quail relate to various function with special relation to the function of the central garay matter as well as a visual function.2.The efferent and afferent connections of the olfactory tuberyculum in chickens were studied using the biocytin method. After biocytin was injected into the unilateral olfactor tuberuculum, labered fibers and terminals were seen in priform cortec, basal nucleus, hyperstriatum accesorium, archistriatum pars ventralis. It was suggested that olfactory system is relate to the food intak … More e behavior throught the priform cortex.3.The cytoarchitecture and distribution pattern of the vagal preganglionic neurons within the dorsal motor nucleus of the vagus nerve innervating the proventriculus and the gizzard of the Japanese quail were examined by Nissle staing and horseradish peroxidase (HRP) methods. After injection of HRP into the ventral and dorsal parts of the proventriculus, HRP labeled cells were predominantly observed in the left and right dorsal vagal nucleus, respectively. The distribution pattern of labeled cells following the injection of HRP into each region of gizzard showed that there was very little differences in the number of neurons between the left and right dorsal vagal moto nucleus, and no topographic localization was found in the dorsal and ventral vagal nucleus. The vagal preganglionic neurons projecting to the gizzard lay more caudal than one for the proventriculus. This study suggested topographic localization in the distribution patterns of the vagal preganglionic neurons innervating the proventriculus and the gizzard. Less

1.用生物胞素顺行法研究了日本鹌鹑视顶盖向脑干的传出纤维。将biocytin注入同侧视顶盖后，在圆核、外侧膝状体腹侧核的神经元部、外侧膝状体背侧核的主体部、丘脑背外侧核的外侧部、中央灰质等处可见标记终末。本研究结果提示，鹌鹑离顶盖冲动与多种功能有关，特别是与视觉功能和中枢Garay物质的功能有关。2.用生物胞素法研究了鸡嗅结节的传出和传入联系。将生物胞素注入一侧嗅结节后，在初级皮质、基底核、副上纹状体、原纹状体腹侧部可见标记纤维和终末。提示嗅觉系统与食物摄入有关 ...更多信息 3.用尼氏染色法和辣根过氧化物酶（HRP）法观察了支配前胃和肌胃的迷走神经运动背核内迷走节前神经元的细胞构筑和分布。将HRP注入腺胃腹侧部和背侧部后，HRP标记细胞主要分布于左、右迷走神经背核。将HRP注入胃各区后，标记细胞的分布模式表明，左右迷走运动背核的神经元数目差异很小，迷走背核和迷走腹核未见局部定位。迷走神经节前神经元投射到砂囊的位置比投射到前胃的位置更靠尾侧。本研究提示支配前胃和肌胃的迷走神经节前神经元的分布模式具有地形定位性。少
