作为一个必不可少的初步的一系列实验研究的传入和传出连接的猴子内嗅皮层，我们已经进行了详细的分析，其cytoarchitectonic组织。首先，根据尼氏染色和纤维染色标本中观察到的特征，补充高尔基体染色材料和用Timm法重金属染色的标本以及乙酰胆碱酯酶组织化学染色的标本，内嗅皮层被分为七个区域，除了一个位于吻侧的区域以其接收的显著输入命名外，其余区域均根据其吻侧和中侧位置命名。嗅球在吻侧水平，内嗅皮层的特点是一些形态不均匀性。神经元倾向于组织成被大的、厚的、放射状定向的纤维束包围的斑块。在尾部水平，内嗅皮层有一个更明显的分层外观，让人想起在新皮层，和大多数的神经元和纤维束排列在离散的径向列。与内嗅皮层横向相邻的皮层区域，通常被称为“嗅周皮层”，实际上由两个独立的区域组成，对应于布罗德曼的35和36区。区域35占据鼻沟的底部和部分侧面。36区从鼻沟外侧延伸到颞下回，在那里它在吻侧与TA和TE区交界，在尾侧与海马旁回的TF区交界。每个内嗅场的表面范围已确定的“展开”的二维地图的区域和测量的面积与计算机化的数字化系统。
As an essential preliminary to a series of experimental studies of the afferent and efferent connections of the monkey entorhinal cortex, we have carried out a detailed analysis of its cytoarchitectonic organization. Primarily on the basis of features observed in Nissl- and fiber-stained preparations, supplemented with Golgi-stained material and preparations stained for heavy metals by Timm''s method and histochemically for acetylcholinesterase, the entorhinal cortex has been divided into seven fields that are named according to their rostrocadual and mediolateral positions except for one rostrally located field that is named for the prominent input that it receives from the olfactory bulb. At rostral levels, the entorhinal cortex is marked by a number of morphological inhomogeneities. The neurons tend to be organized in patches that are surrounded by large, thick, radially oriented bundles of fibers. At caudal levels, the entorhinal cortex has a more distinctly laminated appearance, reminiscent of that in the neocortex, and most of the neurons and fiber fascicles are arranged in discrete radial columns. The cortical region adjoining the entorhinal cortex laterally, which is commonly known as the "perirhinal cortex," is in fact composed of two separate fields corresponding to areas 35 and 36 of Brodmann. Area 35 occupies the fundus and part of the lateral aspect of the rhinal sulcus. Area 36 extends from the lateral bank of the rhinal sulcus into the inferior temporal gyrus, where it borders fields TA and TE rostrally, and field TF of the parahippocampal gyrus caudally. The surface extents of each of the entorhinal fields have been determined by making "unfolded" two-dimensional maps of the region and measuring the areas with a computerized digitizing system.
