In the human primary and secondary auditory cortices the neuron somata are arranged in distinct columnar clusters. Measurements on their diameters and the intervals between them yield significant hemispherical differences, having in all cases greater values in the left hemisphere. Computer-assisted tracings of Golgi-impregnated dendritic trees of 300 neurons show the expected types. An analysis of the columnar structure of the dendritic trees indicates varying degrees of specificity in collecting information from their surroundings. An analysis of their tangential extent shows that in the primary cortices a greater extent in the left hemisphere effectively cancels the differences in columnar widths and intervals, allowing for a similar dendritic connectivity among columns in both hemispheres. In the secondary cortex this connectivity is greater on the right side.
在人类初级和次级听觉皮层中，神经元胞体排列成明显的柱状簇。对其直径及其之间间隔的测量产生了显著的半球差异，在所有情况下左半球的值都更大。对300个神经元的高尔基浸染树突的计算机辅助追踪显示出预期的类型。对树突柱状结构的分析表明，从周围环境收集信息时具有不同程度的特异性。对其切线范围的分析表明，在初级皮层中，左半球更大的范围有效地消除了柱状宽度和间隔的差异，使得两个半球的柱状之间具有相似的树突连接性。在次级皮层中，右侧的这种连接性更强。
