1.采用伪随机宽度的二元光栅，在多个方向上移动通过感受野，研究了鲶鱼（Ictalurus punctatus）神经节细胞感受野。2.神经节细胞根据其感受野的大小和复杂性分为两组。第一组，B细胞，拥有狭窄和明确的简单的感受野的所有方向的刺激运动。第二组，A细胞，表现出广泛的，不对称的和复杂的感受野与各向异性的行为，为某些方向的刺激运动。3.许多A细胞表现出微妙的方向敏感性，这是它们一般的整体反应特征的一部分。此外，一小部分A细胞和B细胞表现出方向敏感性反应。4. B细胞的简单感受野类似于双极细胞感受野。以前的解剖学和生理学研究表明，这些细胞主要接受双极细胞输入。另一方面，A细胞的复合感受野更类似于无长突细胞感受野。很可能这些细胞主要从无长突细胞接收输入。这一区别也纳入了分类办法。
1. Receptive fields of catfish (Ictalurus punctatus) ganglion cells were studied using a pseudorandom-width binary grating that was moved through the receptive field in a number of directions. 2. Ganglion cells were divided into two groups according to the size and complexity of their receptive fields. The first group, B-cells, possessed narrow and well-defined simple receptive fields for all directions of stimulus movement. The second group, A-cells, showed wide, asymmetric and complex receptive fields with anisotropic behavior for certain directions of stimulus movement. 3. Many A-cells showed a subtle orientation sensitivity as a part of their general, overall response profile. In addition, a small percentage of A-and B-cells showed directionally sensitive responses. 4. The simple receptive fields of the B-cells appeared similar to bipolar cell receptive fields. Previous anatomical and physiological studies suggest these cells receive primarily bipolar cell input. On the other hand, the complex receptive fields of the A-cells appeared more similar to amacrine cell receptive fields. It is likely these cells receive their input mainly from amacrine cells. This distinction was also incorporated into the classification scheme.
