Golgi and axonal transport techniques have been used to examine the organization of neurons within primary visual cortex, area 17, of the cat. This organization has been compared to that of the primate cortical area 17 as described in previous studies and it is discussed in relationship to the distribution of afferents from the dorsal lateral geniculate nucleus (dLGN). The visual cortex of the cat and monkey show strong similarities in the laminar positions of neurons projecting extrinsically and also in the restriction of spiny stellate neurons to a central lamina (lamina 4) receiving input from the dLGN. However, lamina 4B in the monkey, which contains spiny stellate neurons but does not receive direct input from the dLGN, has no direct counterpart in cat area 17. Axon projections of spiny stellate neurons in the other divisions of lamina 4 differ in cat and monkey: the small, closely packed neurons in the lowermost division of lamina 4 (4B in the cat, 4Cbeta in the monkey) project chiefly within lamina 4 in the cat whereas in the monkey they have a strong projection to lamina 3. In the cat, spiny stellate neurons of lamina 4A project upon lamina 3 whereas in the monkey those in the apparently equivalent zone, 4Calpha, project upon lamina 4B. Most non-spiny stellate neurons examined have precisely organized interlaminar axonal projections which differ from the axon trajectories of neighboring spiny neurons.
高尔基体染色法和轴突运输技术已被用于研究猫初级视皮层17区（area 17）内神经元的组织构造。该组织构造已与先前研究中所描述的灵长类动物皮层17区的组织构造进行了比较，并结合背外侧膝状核（dLGN）传入纤维的分布进行了讨论。猫和猴的视皮层在向外投射神经元的分层位置上，以及在将棘状星形神经元限制于接受dLGN输入的中央层（第4层）方面，表现出强烈的相似性。然而，猴的第4B层含有棘状星形神经元，但不接受dLGN的直接输入，在猫的17区没有直接对应的结构。猫和猴的第4层其他分区中棘状星形神经元的轴突投射有所不同：第4层最下部（猫的4B层，猴的4Cβ层）中紧密排列的小神经元在猫中主要投射到第4层内，而在猴中它们有很强的投射到第3层。在猫中，第4A层的棘状星形神经元投射到第3层，而在猴中，明显等效区域（4Cα层）的棘状星形神经元投射到第4B层。大多数被检测的非棘状星形神经元具有精确组织的层间轴突投射，这与相邻棘状神经元的轴突轨迹不同。
