Relation between the digestive organ, and Visual and olfactory Center in the foal

1.用顺行生物细胞素法研究了日本鸣禽顶盖至脑干的差异。在同侧视顶盖注射生物细胞素后，圆形核、腹侧膝状核神经纤维部、膝状背外侧核主体部分、丘脑背外侧核外侧部、中央灰质均可见标记终末。这些结果表明，鹌鹑的顶盖分离冲动与多种功能有关，特别是与中央加雷物质的功能和视觉功能有关。2.用生物细胞素法研究了雏鸡嗅结节的传出和传出联系。将生物细胞素注入单侧Olfactor结节后，在原皮层、基底核、高纹状体、腹侧部可见标记纤维和终末。提示嗅觉系统与食物摄取…有关。用Nissle标记法和辣根过氧化物酶(HRP)法研究了日本鸣禽迷走神经背侧运动核内支配前胃和胃的迷走神经节前神经元的细胞构筑和分布模式。将HRP注入腺胃腹侧部和背侧部后，在左侧迷走神经背侧核和右侧迷走神经背侧核分别可见大量HRP标记细胞。在肌胃各区注射HRP后标记细胞的分布模式显示，左右迷走神经背侧运动核之间的神经元数量差异不大，迷走神经背侧核和腹侧核未见局部定位。投射到肌胃的迷走神经节前神经元比投射到腺胃的迷走神经节前神经元更靠近尾侧。本研究提示支配腺胃和胃的迷走神经节前神经元的分布模式具有地形性定位。较少

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
