1.利用条件性抑制行为技术，对8只猫的逆相正弦波栅进行了时空对比敏感度的测量。其中正常饲养猫2只，双侧皮质17区和18区部分切除前后各2只，全黑暗饲养猫2只，双眼眼睑缝合猫2只，单眼眼睑缝合猫2只，对照正常饲养猫的术前资料，评价皮质损伤或视力剥夺所致的视力障碍。2.皮质损伤对猫的视觉能力几乎没有定性影响。对比度敏感度在较高而不是较低的空间频率下降低，这可以简洁地描述为空间敏感度的丧失。深色饲养和双眼缝合的猫表现出比皮质消融动物更差的视觉能力。这两种形式的双眼剥夺产生的对比敏感度基本相似，包括在所有空间和时间频率上的显着敏感度损失。受影响的远不止是高空间频率，这种弱视不能简单地描述为空间敏锐度的丧失。4.与非剥夺眼相比，单眼缝合的猫具有正常的视力和对比敏感度，但对于剥夺眼，它们表现出最严重的弱视和最差的对比敏感度。同样，所有空间和时间频率的灵敏度损失都很明显，这一点
1. We used the behavioral technique of conditioned suppression to measure spatial and temporal contrast sensitivity to counterphased, sine-wave gratings in eight cats. These included two normally reared cats before and after bilateral ablations of cortical area 17 and part of area 18, two cats raised in total darkness, two cats raised with binocular lid suture, and two cats raised with monocular lid suture, Visual deficits induced by cortical lesions or visual deprivation were evaluated with respect to the preoperative data of the normally reared cats. 2. The cortical lesions had virtually no qualitative effect on the cat’s visual capacities. Contrast sensitivity was reduced at higher but not lower spatial frequencies, and this can be described succinctly as a loss of spatial acuity.3. Dark-reared and binocularly sutured cats qualitatively exhibited poorer visual capacity than that of the cortically ablated animals. The contrast sensitivity resultant from these two forms of binocular deprivation was basically similar and consisted of significant sensitivity losses at all spatial and temporal frequencies. Much more than high spatial frequencies was affected, and this amblyopia cannot be characterized simply as a spatial acuity loss. 4. Monocularly sutured cats had normal vision and contrast sensitivity with the nondeprived eye, but with the deprived eye they displayed the most severe amblyopia and poorest contrast sensitivity of any of the cats. Again, sensitivity losses were evident for all spatial and temporal frequencies, and this
