记录是从轻度麻醉猫的纹状皮质中的单细胞中进行的。视网膜分别或同时刺激不同大小和形状的光点。在光适应状态下，皮质细胞在没有额外光刺激的情况下是活跃的。增加麻醉深度往往会抑制这种维持的活动。受光影响单个皮层单位放电的感受野通常分为相互拮抗的兴奋区和抑制区。兴奋性和抑制性区域，映射的静态刺激，安排在一个感受野中的并排的方式，与一个类型的中心区域两侧的拮抗领域。一个单位的有效驱动需要一个特定的形式，大小，位置和方向的刺激，在感受野内的兴奋和抑制区域的安排的基础上。双眼激活的单位从两个视网膜中大致同源的区域驱动。对于每一个单位的领域映射的两只眼睛是相似的大小，形式和方向，并与移动点刺激时，表现出类似的方向偏好。在一个双眼单位中，两个感受野的兴奋区和抑制区相互作用，可以像在一个单一的视野中一样表现为相加和相互拮抗。
Recordings were made from single cells in the striate cortex of lightly anesthetized cats. The retinas were stimulated separately or simultaneously with light spots of various sizes and shapes. In the light-adapted state cortical cells were active in the absence of additional light stimulation. Increasing the depth of anesthesia tended to suppress this maintained activity. Receptive fields which on illumination influenced the firing of single cortical units were usually subdivided into mutually antagonistic excitatory and inhibitory regions. Excitatory and inhibitory regions, as mapped by stationary stimuli, were arranged within a receptive field in a side-by-side fashion, with a central area of one type flanked by antagonistic areas. Effective driving of a unit required a stimulus specific in form, size, position and orientation, based on the arrangement of excitatory and inhibitory regions within receptive fields. Binocularly activated units were driven from roughly homologous regions in the two retinas. For each unit the fields mapped for the two eyes were similar in size, form and orientation, and when stimulated with moving spots, showed similar directional preferences. In a binocular unit excitatory and inhibitory regions of the two receptive fields interacted, and summation and mutual antagonism could be shown just as within a single field.
