In a program of surveying the characteristics of visual receptive fields of neurons in rabbit brain, we have explored cortical sectors beyond the striate and occipital cortices and found cells in a part of the temporal lobe that were responsive to visual stimulation. Using evoked potential and unit-cluster methods, this temporal visual area was mapped to be roughly oval-shaped, 3 mm x 2mm in size, and at about the level posterior to the apex region of auditory area 1. It is located ventral to and continuous with visual area 11, at about the caudal half of M. Rose's temporal cortices 1 and 2 (T1 and T2). Only about two-thirds of 96 units studied responded to some sort of moving light stimulation. These motion-sensitive cells were divided into four groups. Cells in the first group (22) responded best to a large light spot or shadow sweeping quickly across the field. Cells in the second group (29) responded to slow moving, jerking spot. Nine cells responded to a narrow, dark bar thrusting into a lighted field. Four cells are "direction-selective," responding to light stimulus moving in one direction and showing either no response or decreased background discharges in the opposite direction. In addition, three cells required unusual stimulus features. Of the 38 cells tested, nine of them were found to be binocularly driven. These receptive field characteristics are quite different from those described for other visual centers of the rabbit. The significance of these results together with data on the anatomical connections of this cortical area as reported in the following paper were discussed.
在一项对兔脑神经元视觉感受野特征进行研究的项目中，我们探索了纹状皮层和枕叶皮层以外的皮质区域，发现在颞叶的一部分区域存在对视觉刺激有反应的细胞。利用诱发电位和单位簇方法，将这个颞叶视觉区域描绘为大致椭圆形，大小为3毫米×2毫米，位于听觉1区尖部区域后方约同一水平。它位于11区视觉区域的腹侧并与之相连，大约在罗斯颞叶皮层1和2（T1和T2）的尾侧一半处。在研究的96个单位中，只有约三分之二对某种移动光刺激有反应。这些对运动敏感的细胞分为四组。第一组（22个）细胞对快速扫过视野的大光斑或阴影反应最佳。第二组（29个）细胞对缓慢移动、有急拉动作的光斑有反应。9个细胞对插入亮场的窄暗条有反应。4个细胞是“方向选择性”的，对向一个方向移动的光刺激有反应，而对相反方向的光刺激则无反应或背景放电减少。此外，3个细胞需要特殊的刺激特征。在测试的38个细胞中，发现有9个是双眼驱动的。这些感受野特征与兔的其他视觉中枢所描述的特征有很大不同。本文将讨论这些结果的意义以及如下一篇论文中所报道的关于这个皮质区域解剖学连接的数据。
