The intrinsic organization of the receptive fields of simple striate cells revealed by moving stimuli is much more complex than could have been suspected from the use of stationary ones. There is, in fact, a small excitatory region centrally located in these receptive fields and an inhibitory region encompassing the whole excitatory component. These inhibitory regions or "inhibitory sidebands", were identified by stimulating the cells with bars of light against an artificial background discharge produced by repeated asynchronous stimulation of the excitatory component of the cell's receptive field. For a long time these inhibitory sidebands have been accounted for on the basis of the receptive field ON/OFF antagonism. These inhibitory regions, instead, are activated by both stationary and moving stimuli. Therefore, besides the antagonistic component a non-antagonistic one, purely inhibitory, greatly contributes to their origin.
移动刺激所揭示的简单视皮层细胞感受野的内在组织，比使用静止刺激时所推测的要复杂得多。事实上，在这些感受野的中心位置有一个小的兴奋区域，以及一个包围整个兴奋成分的抑制区域。这些抑制区域或“抑制性边带”，是通过用光条刺激细胞来识别的，同时细胞感受野的兴奋成分受到重复异步刺激产生人工背景放电。长期以来，这些抑制性边带一直基于感受野的开/关拮抗作用来解释。相反，这些抑制区域可由静止和移动刺激激活。因此，除了拮抗成分外，一个纯抑制性的非拮抗成分对它们的产生也有很大作用。
