Organization of neurons in Clare-Bishop associative cortex was investigated by means of microelectrode vertical penetrations and recording of the neuronal responses to visual stimulation. Of 463 electrode penetrations 255 showed responses to visual stimulation. In 131 penetrations only 1 or 2 visually driven neurons were noted, in 55 cases more than 3 neurons were registered. Of 55 investigated penetrations 8 showed distinct columnar organization, i.e. all neurons in each column had similar characteristics. In 24 penetrations neurons were organized in groups of 2 or 3 similar neurons intermingled with neurons of other types. In 18 penetrations a great degree of overlapping of the receptive fields of neurons in a single column was observed. In 5 penetrations a chaotic organization of different neurons was found. A conclusion is made that the columnar organization of visually driven neurons as a functional cortical unit can not be regarded as a prominent feature in Clare-Bishop area.
通过微电极垂直插入并记录神经元对视觉刺激的反应，对克莱尔 - 毕晓普联合皮层中的神经元组织进行了研究。在463次电极插入中，255次显示出对视觉刺激的反应。在131次插入中，仅记录到1或2个视觉驱动神经元，在55例中记录到3个以上神经元。在55次研究的插入中，8次显示出明显的柱状组织，即每列中的所有神经元具有相似的特征。在24次插入中，神经元以2或3个相似神经元的组形式组织，与其他类型的神经元混合在一起。在18次插入中，观察到单列中神经元感受野的高度重叠。在5次插入中，发现不同神经元的混乱组织。得出的结论是，作为功能性皮层单位的视觉驱动神经元的柱状组织不能被视为克莱尔 - 毕晓普区域的突出特征。
