在幼猫的纹状皮层中研究了单个细胞对视觉刺激的反应。两只分别为8天和16天大的幼猫此前未接触过有图案的刺激。这些幼猫皮层细胞的反应与成年猫惊人地相似。感受野是“简单”或“复杂”的，具有明确的感受野方向。方向相似的细胞似乎分组在柱状区域。大多数细胞受双眼驱动，双眼相互作用的模式与成年猫相似。与成年猫相比，细胞对视觉刺激的反应稍显迟缓，感受野方向往往不那么明确。在另外两只幼猫中，一只从出生起就被半透明眼罩单眼剥夺视力19天，另一只为正常的20天幼猫，按照成年猫的标准，它们任一只眼睛对有图案刺激的反应都是完全正常的。结论是，即使没有有图案的视觉经验，负责纹状皮层细胞高度组织化行为的许多连接在出生时或出生后几天内就一定存在。
Responses of single cells to visual stimuli were studied in the striate cortex of very young kitten. Two animals, aged 8 and 16 days, had no previous exposure to patterned stimuli. Responses of cortical cells in these animals were strikingly similar to those of adult cats. Fields were "simple" or "complex", with a clear receptive-field orientation. Cells with similar orientations appeared to be grouped in columnar regions. The majority of cells were driven by the two eyes, with patterns of binocular interaction that were similar to those in the adult. Compared with the mature cat, cells responded somewhat more sluggishly to visual stimuli, and receptive-field orientations tended to be not quite so well defined. In two other kittens, one monocularly deprived by translucent occluder from birth for 19 days, the other a normal 20-day-old, responses to patterned stimulation of either eye were entirely normal by adult standards. It is concluded that many of the connections responsible for the highly organized behavior of cells in the striate cortex must be present in birth or within a few days of it, even in the absence of patterned visual experience.
