十三只戴兜帽的老鼠被训练来区分静止或移动的垂直黑白条纹图案以及与总光通量匹配的均匀灰色刺激。然后，7 只动物的纹状皮层被切除，其余 6 只动物的背外侧额叶皮层被切除。额叶皮层受损的动物重新学习了这项任务，并取得了显着的积极成果。所有去除了纹状皮层的动物都成功地重新学习了辨别力，尽管储蓄量为负。对照测试表明，动物不会根据任何不受控制的亮度差异进行区分。
Thirteen hooded rats were trained to discriminate between either a pattern of stationary or moving vertical black and white stripes and a uniform grey stimulus matched for total luminous flux. The striate cortex was then removed in 7 animals, and the dorsolateral frontal cortex in the remaining 6. Animals with frontal cortical lesions relearned the task with substantial positive savings. All animals with striate cortex removed succeeded in relearning the discrimination, although with negative savings. Control tests showed that the animals were not discriminating on the basis of any uncontrolled differences in luminosity.
