According to a modern view, simple cells of the cat striate cortex are considered to operate as a part of Fourier analysis system thus leading to the idea that the operational mechanism of the visual cortex is concerned with the analysis of spatial frequencies. Nevertheless if simple cells are really concerned only with the analysis of spatial frequencies there should exist a strict relationship between their spatial frequency selectivity and the spatial organization of their receptive fields. This is because it is the spatial organization of the spatial frequency detector i.e. the cell's receptive field that determines the cell's spatial frequency selectivity. Since the quantitative analysis of the spatial organization of simple cell receptive fields has shown that the receptive fields of these cells are made up of two to four antagonistic subregions it follows that striate simple cells are concerned with the analysis of only a selected range of spatial frequencies. Therefore striate simple cells must be considered analysers of visual signals both in spatial frequencies as well as in spatial positions.
根据现代观点，猫纹状皮层的简单细胞被认为是作为傅里叶分析系统的一部分发挥作用，从而引出了视觉皮层的运作机制与空间频率分析有关的观点。然而，如果简单细胞真的只与空间频率分析有关，那么它们的空间频率选择性与其感受野的空间组织之间应该存在严格的关系。这是因为正是空间频率探测器（即细胞的感受野）的空间组织决定了细胞的空间频率选择性。由于对简单细胞感受野空间组织的定量分析表明，这些细胞的感受野由两到四个拮抗性子区域组成，因此纹状简单细胞只涉及对选定空间频率范围的分析。因此，必须将纹状简单细胞视为视觉信号在空间频率以及空间位置方面的分析器。
