A study of the morphology and laminar distribution of nonpyramidal neurons in Golgi-Nissl preparations of electrophysiologically verified auditory cortex was carried out in the adult rabbit. Nonpyramidal neurons were located primarily within laminae I-IV and were only infrequently seen in lamina V and VI. In lamina I, four nonpyramidal cell types were observed: (1) small, spine-free horizontal neurons, (2) small, sparsely spined multipolar neurons with radiate dendrites, (3) large, multipolar neurons with fusiform somata and vertically aligned, sparsely spined dendrites, and (4) small, spine-free neurogliform neurons. The horizontal and small multipolar neurons had tangentially running axons confined to lamina I. The large, fusiform cells had descending axons which arborized in lamina II and occasionally reached lamina III. In lamina II and the upper part of lamina III, seven nonpyramidal cell types were observed: (1) spine-free bipolar neurons with vertically aligned dendrites and axonal arbors; (2) large, (3) medium, and (4) small, spine-free and sparsely spined multipolar neurons, all with locally ramifying axons; (5) pear-shaped cells with highly oriented dendrites which branched toward the pial surface and vertically arborizing axons; (6) multipolar cells with tangentially and vertically oriented dendrites and ascending axons which entered lamina I, and (7) tufted cells with local axons. Three types of nonpyramidal cells were observed in lamina IV and the lower part of lamina III: (1) large, multipolar cells with radiate, spine-free dendrites and stout axons which arborized locally, (2) spiny multipolar cells with vertically aligned dendrites and ascending axons which arborized in lamina II and III via long horizontal collaterals, and (3) spine-free bipolar cells with vertical dendrites and axons which arborized in a narrow vertical column adjacent to the dendrites. Nonpyramidal neurons in lamina V and VI were primarily multipolar cells with sparsely spined and spine-free dendrites. A comparison of these data with those of other species indicates that the neuronal organization of the rabbit auditory cortex is similar to that of the sensory cortex of the rodent but is strikingly different from that of carnivores and primates.
在成年兔身上，对经电生理验证的听觉皮层的高尔基-尼氏体染色标本中的非锥体神经元的形态和分层分布进行了研究。非锥体神经元主要位于I-IV层，在V层和VI层中很少见到。在I层中，观察到四种非锥体细胞类型：(1) 小的、无棘的水平神经元；(2) 小的、有稀疏棘的多极神经元，其树突呈放射状；(3) 大的、多极神经元，其胞体呈梭形，树突垂直排列且有稀疏的棘；(4) 小的、无棘的神经胶质样神经元。水平神经元和小多极神经元的轴突沿切线方向走行，局限于I层。大的梭形细胞有下行轴突，在II层分支，偶尔到达III层。在II层和III层上部，观察到七种非锥体细胞类型：(1) 无棘的双极神经元，其树突和轴突分支垂直排列；(2) 大的；(3) 中等的；(4) 小的，无棘和有稀疏棘的多极神经元，它们的轴突都在局部分支；(5) 梨形细胞，其树突高度定向，向软膜表面分支，轴突垂直分支；(6) 多极细胞，其树突沿切线和垂直方向排列，轴突向上进入I层；(7) 簇状细胞，其轴突在局部。在IV层和III层下部观察到三种非锥体细胞类型：(1) 大的多极细胞，其树突无棘且呈放射状，轴突粗壮，在局部分支；(2) 有棘的多极细胞，其树突垂直排列，轴突向上，通过长的水平侧支在II层和III层分支；(3) 无棘的双极细胞，其树突和轴突垂直，轴突在与树突相邻的狭窄垂直柱内分支。V层和VI层中的非锥体神经元主要是多极细胞，其树突有稀疏的棘和无棘。将这些数据与其他物种的数据进行比较表明，兔听觉皮层的神经元组织与啮齿动物的感觉皮层相似，但与食肉动物和灵长类动物的明显不同。
