The effects of lesions in the striate or extra-striate visual cortex of cats were evaluated using visual discrimination problems which required either local or global pattern processing. The results indicate that damage to areas 17 and 18 preferentially impairs local processes, while in addition they suggest that damage to the extra-striate cortex preferentially affects global processing. These findings may be related to the observations that cats with large lesions in the extra-striate cortex demonstrate deficits in form perception without reductions in visual acuity and those with lesions in areas 17-18 show elevations of acuity thresholds while maintaining excellent pattern and form vision.
利用需要局部或整体模式处理的视觉辨别问题，评估了猫的纹状或纹状外视觉皮层损伤的影响。结果表明，17区和18区的损伤优先损害局部处理，此外还表明，纹状外皮层的损伤优先影响整体处理。这些发现可能与以下观察结果有关：纹状外皮层有大面积损伤的猫在视力没有下降的情况下表现出形状感知缺陷，而17 - 18区有损伤的猫在保持良好的图案和形状视觉的同时，视力阈值升高。
