在猕猴的颞上平面上绘制了神经元和神经元簇的最佳频率分布。初级听觉皮层（A1）包括完整有序的耳蜗表征。它与通常被称为koniocortex的细胞结构场共展。耳蜗尖部（低频）位于耳蜗场内的喙侧，耳蜗基部（高频）位于耳蜗尾侧。耳蜗分区的一小块区域位于听觉皮层带中；也就是说，具有非常相似的最佳频率的神经元被垂直和水平排列。在A1周围发现了其他在解剖学和生理学上与主要场分开的场。在其中两个实验中，数据显示了它们在地形上的组织方式。此外，在颞上回的平面和外侧表面上，似乎有听觉区进一步向后方延伸。
The distribution of best frequencies of neurons and neuron clusters was mapped on the superior temporal plane of the macaque monkey. Primary auditory cortex (A1) comprises a complete and orderly cochlear representation. It is coextensive with a cytoarchitectonic field often referred to as koniocortex. Cochlear apex (low frequency) is represented rostrolaterally within the field and cochlear base (high frequency) caudomedially. A small region of the cochlear partition is found represented in a band of auditory cortex; that is neurons with very similar best frequencies are arrayed both vertically and horizontally. Surrounding A1 4 other fields are found that on both anatomical and physiological grounds stand apart from the primary field. In two of them the data suggest the way in which they are topographically organized. In addition there appear to be auditory areas extending further rostrally on the plane and onto the lateral surface of the superior temporal gyrus.
