Columnar structure in the cerebral cortex has been demonstrated in numerous studies. However, in the visual system, it is not clear from imaging, basic physiological and anatomical approaches how multiple stimulus parameters are related within columns. We have analyzed recordings from pairs of neurons in the striate cortex of the cat using various spatial and temporal parameters. We find that most parameters are clustered within inferred columns with the exception of spatial phase. Diversity of phase could be useful for serial processing in central visual pathways.
在众多研究中已证实大脑皮层存在柱状结构。然而，在视觉系统中，从成像、基础生理学和解剖学方法尚不清楚在柱内多种刺激参数是如何关联的。我们使用各种空间和时间参数分析了猫纹状皮层中神经元对的记录。我们发现，除空间相位外，大多数参数都聚集在推断出的柱内。相位的多样性可能对中枢视觉通路中的串行处理有用。
