The spatiotemporal organization of receptive fields (RF) of the cats lateral geniculate cells was investigated under several scotopic and mesopic light adaptation levels, using stationary and moving light stimuli. A given adaptation level was reached by changing of either the diffuse background or the adapting central spot intensity. Both methods gave the same qualitative results. The RFs were prominently reorganized after dark adaptation. Under such conditions, the central response area was enlarged and the classic excitatory and inhibitory surrounds were hardly visible in most cases. A minimum light level was needed for developing classic surrounds. Both inhibitory and excitatory surrounds changed their spatial positions simultaneously at higher light adaptation levels. ON- and OFF-center cells changed their spatiotemporal organization similarly, thus indicating similar underlying mechanisms.
利用静止和移动光刺激，在几种暗视和明视适应水平下，研究了猫外侧膝状体细胞感受野（RF）的时空组织。通过改变漫射背景或适应中心光斑强度来达到给定的适应水平。两种方法得到的定性结果相同。暗适应后，感受野显著重组。在这种情况下，中央反应区域扩大，在大多数情况下，经典的兴奋和抑制性周边几乎不可见。形成经典周边需要最低光水平。在较高光适应水平下，抑制性和兴奋性周边同时改变其空间位置。ON中心和OFF中心细胞的时空组织变化相似，因此表明潜在机制相似。
