虽然具有相似功能特性的皮层神经元通常聚集在一个柱状组织中，但在人类初级视觉皮层（V1）中只发现了眼优势柱，即代表分离的解剖输入（来自两只眼睛中的一只）的柱状结构。它还有待证明，是否其他柱状组织，只产生于不同的反应，刺激属性也存在于人类V1。使用高分辨率的功能磁共振成像，我们已经发现了这样一个功能架构包含域，优先响应于低或高的时间频率。
Although cortical neurons with similar functional properties often cluster together in a columnar organization, only ocular dominance columns, the columnar structure representing segregated anatomical input (from one of the two eyes), have been found in human primary visual cortex (V1). It has yet to be shown whether other columnar organizations that arise only from differential responses to stimulus properties also exist in human V1. Using high-resolution functional magnetic resonance imaging, we have found such a functional architecture containing domains that respond preferentially to either low or high temporal frequency.
