一项研究以 18 只猫为受试者，调查双侧小脑半球皮质消融对明暗辨别学习的影响。手术对照组（8只动物）中，5只在术后两周进行测试，3只在术后三周进行测试。实验组（10 只动物）中，4 只在术后两周进行测试，6 只在术后三周进行测试。辨别任务包括仪器调节的压杠反应。结果显示，几乎在整个 23 天的学习期间，实验猫在辨别任务上的表现都比对照猫差。据推测，两组动物之间的差异源于小脑与习惯化过程中涉及的其他结构之间的连接的干扰（由消融引起）。
Eighteen cats were used as subjects in a study which investigated the effects of bilateral cortical cerebellar hemispheric ablations upon light-dark discrimination learning. From the operated control group (8 animals), 5 were tested two weeks and 3 three weeks postoperatively. From the experimental group (10 animals) 4 were tested two weeks and 6 three weeks postoperatively. The discrimination task consisted of an instrumentally conditioned bar-pressing response. The results showed that almost during the entire 23-day learning period, the experimental cats performed more poorly on the discrimination task than their controls. It is hypothesized that the difference between the two groups of animals derives from the disturbance (caused by the ablation) of the connections between the cerebellum and other structures involved in the habituation process.
