在猫中测试了连续双侧消融大脑皮层中的外侧回和后外侧回以及上级丘后视觉强度（通量）辨别的保留。其效果部分取决于消融的顺序。在皮层消融后重新学习辨别，无论其是否跟随顶盖损伤，都需要原始试验次数的1-2倍。丘病变对强度辨别力的保持没有影响，除非它之前有皮质病变，在这种情况下，学习缺陷比皮质病变后更严重。
The retention of a visual intensity (flux) discrimination after serial bilateral ablations of the lateral and posterolateral gyri in the cerebral cortex and of the superior colliculi was tested in cats. The effects depended, in part, on the order of the ablations. Relearning the discrimination after the cortical ablation, whether or not it follows the tectal lesion, takes 1-2 times the original number of trials. The collicular lesion has no effect on retention of the intensity discrimination unless it is preceded by the cortical lesion, in which case the learning deficit is more severe than following the cortical lesion.
