The somatosensory barrels in layer IV of rat cerebral cortex were studied on uniformly oriented, serial, tangential sections by a combination of light microscope and ultrastructural techniques. Section orientation between sections was maintained by blood vessel patterns. The principal elements of both anterior and posterior barrels were quantified and analyzed in relation to proportional content and nonrandom spatial arrangement over depth in layer IV. Elements studied in this manner included neurons, myelinated axons, apical dendrites, synapses, glial cells, and blood vessels. In general, constituents were found to be arranged in a highly ordered fashion similar to other discretely organized sensory cortical areas. Myelinated axons outlined the basic structure of the barrels with the osmium staining employed. Neurons appeared organized in small clusters. In addition apical dendrites, synapses, and blood vessels also exhibited nonrandom distribution complementary to the organization of axons and neurons. Anterior and posterior barrels differed slightly in their organization of elements.
通过光学显微镜和超微结构技术相结合的方法，在大鼠大脑皮层IV层的均匀定向连续切向切片上研究了体感桶。切片之间的方向通过血管模式来维持。对前桶和后桶的主要成分进行了量化和分析，涉及IV层深度上的比例含量和非随机空间排列。以这种方式研究的成分包括神经元、有髓轴突、顶端树突、突触、神经胶质细胞和血管。一般来说，发现这些成分以高度有序的方式排列，类似于其他离散组织的感觉皮层区域。使用锇染色时，有髓轴突勾勒出桶的基本结构。神经元似乎成小簇排列。此外，顶端树突、突触和血管也表现出与轴突和神经元组织互补的非随机分布。前桶和后桶在其成分组织上略有不同。
