Cells in the simple family respond to a moving light bar with an average response histogram that is most commonly unimodal (single peak: encounter frequency, 64%) and less commonly bimodal (33%) or trimodal (3%). The mean width of the principal response peak given by hypercomplex I cells is narrower than that of simple cells and they have a lower mean optimal stimulus velocity. In a series of 74 cells (simple, 47; hypercomplex I, 27), detailed comparison of the spatial relations between the response peaks to the moving bar and the subregions to the stationary flashing bar led to the concept of a boundary response. The term "boundary response" refers to an isolated response peak occurring as a moving light bar leaves an OFF subregion that is the last in the sequence of subregions traversed by the bar. The presence of a boundary response leads to an apparent discrepancy between the number of response peaks to a moving light bar and the number of ON subregions in the static-field plot. The boundary response is necessarily completely direction selective. A detailed comparison of the properties of cells as revealed by hand and quantitative methods showed a very good agreement between the two methods in respect to the assignment of cells to the simple, B- and complex cell families. There were, however, serious discrepancies in respect to the receptive field organization of cells in the simple family.(ABSTRACT TRUNCATED AT 250 WORDS)
简单细胞家族中的细胞对移动的光条的反应具有平均反应直方图，其最常见的是单峰（单峰：遭遇频率为64%），较少见的是双峰（33%）或三峰（3%）。超复杂I细胞给出的主要反应峰的平均宽度比简单细胞的窄，并且它们具有较低的平均最佳刺激速度。在一系列74个细胞（简单细胞47个；超复杂I细胞27个）中，对移动光条的反应峰与静止闪烁光条的子区域之间的空间关系进行详细比较，得出了边界反应的概念。“边界反应”一词指的是当移动的光条离开一个关闭子区域时出现的孤立反应峰，该关闭子区域是光条穿过的子区域序列中的最后一个。边界反应的存在导致对移动光条的反应峰数量与静态场图中开启子区域数量之间出现明显差异。边界反应必然是完全方向选择性的。对手动和定量方法所揭示的细胞特性进行详细比较表明，在将细胞归类为简单细胞、B细胞和复杂细胞家族方面，这两种方法非常吻合。然而，在简单细胞家族中细胞的感受野组织方面存在严重差异。（摘要截短至250字）
