A square-wave grating from which the fundamental harmonic has been subtracted (missing fundamental grating) when viewed from a suitable distance appears similar to another grating of periodicity three times higher. The neurons of the visual cortex of the cat, in a given range of spatial frequencies characteristic of each cell, give similar responses to the two gratings.
从适当距离观察时，一个减去了基波谐波的方波光栅（缺基波光栅）看起来类似于周期性高三倍的另一个光栅。在猫视觉皮层中，在每个细胞特有的特定空间频率范围内，神经元对这两种光栅给出相似的反应。
