从同一微电极位置同时记录和分离的猫视皮层相邻的简单细胞通常被调谐到相同的方向和空间频率。这些空间频率对的成员漂移正弦波光栅的响应是互相关的。在空间频率选择性曲线的中间范围内，成对细胞的响应在相位上相差约90 °。调谐到相同空间频率和方向的相邻简单细胞可以表示成对的正弦和余弦滤波器，就其对传入空间输入的处理而言，以及截断的正弦和余弦滤波器，就简单细胞的输出而言。
Adjacent simple cells of cat visual cortex recorded and isolated simultaneously from the same microelectrode placement were usually tuned to the same orientation and spatial frequency. The responses of the members of these spatial frequency pairs to drifting sine-wave gratings were cross-correlated. Within the middle range of the spatial frequency selectivity curves, the responses of the paired cells differed in phase by approximately 90.degree.. Adjacent simple cells tuned to the same spatial frequency and orientation may represent paired sine and cosine filters in terms of their processing of afferent spatial inputs and truncated sine and cosine filters in terms of the output of simple cells.
