The present investigation systematically analyzes the course and arrangement of dendrites in lamina II/III of the visual and the motor cortex of the rabbit on the basis of Klüver-PAS stained 10 micron paraffin sections, 1 micron plastic-embedded semithin sections and ultrathin sections. In both areas the dendritic pattern of lamina II/III is characterized by vertical bundles reminiscent of the pattern in lamina IV/V. The bundles form in the upper half of lamina II/III. They consist mainly of apical dendrites from lamina II/III pyramidal cells and receive branches from dendrite bundles in lamina IV/V, i.e., branches from apical dendrites arising from lamina V pyramidal cells. Besides these features in common, the lamina II/III bundles in the visual cortex on the one hand and in the motor cortex on the other differ with regards to the size and shape of individual bundles as well as to the extent of connections with bundles in lamina IV/V.
本研究基于克吕弗-过碘酸希夫（Klüver-PAS）染色的10微米石蜡切片、1微米塑料包埋半薄切片和超薄切片，系统分析了家兔视觉皮层和运动皮层II/III层中树突的走向和排列。在这两个区域中，II/III层的树突模式的特征是垂直束状结构，这让人联想到IV/V层中的模式。这些束状结构在II/III层的上半部分形成。它们主要由II/III层锥体细胞的顶端树突组成，并接收来自IV/V层树突束的分支，即来自V层锥体细胞顶端树突的分支。除了这些共同特征外，视觉皮层和运动皮层的II/III层束状结构在单个束状结构的大小和形状以及与IV/V层束状结构的连接程度方面存在差异。
