Two groups of 10 hooded rats were trained on a pattern discrimination between horizontal and vertical striped stimuli which were equated for contour-length and total luminous flux, and in which consistent local luminous flux cues were eliminated. In one group of rats, visual cortex removals were performed in two stages with training between the operations. Nine out of the 10 rats were able to relearn the pattern discrimination (median of 344 trials) after the completed bilateral visual cortex lesions in one stage. In agreement with previous studies, none of these animals were able to relearn the discrimination after more than 10 times (550 trial limit) the trials required for original learning. However, several rats with total one-stage lesions could relearn the pattern discrimination if very extended periods of training were given.
将两组各10只带帽大鼠训练以区分水平和垂直条纹刺激的图案，这些刺激在轮廓长度和总光通量方面相等，并且消除了一致的局部光通量线索。在一组大鼠中，分两个阶段进行视觉皮层切除，两次手术之间进行训练。10只大鼠中有9只在一个阶段完成双侧视觉皮层损伤后能够重新学习图案辨别（中位数为344次试验）。与先前的研究一致，这些动物中没有一只能够在超过原始学习所需试验次数的10倍（550次试验限制）后重新学习辨别。然而，如果给予非常长的训练期，几只在一个阶段完全损伤的大鼠可以重新学习图案辨别。
