With chronically implanted electrodes, surface negative and deep positive, slowly increasing potentials were recorded in the forelimb area of the motor cortex prior to self-paced movements of the contralateral hand in monkeys. The slow premovement potentials were markedly reduced in size after ablation of the cerebellar hemisphere on the contralateral side to the motor cortex under recording. It was suggested that the cerebellar hemisphere (neocerebellum) participates in preparing the activity of the motor cortex prior to voluntary movements.
对于长期植入电极的情况，在猴子对侧手进行自主运动之前，在运动皮层的前肢区域记录到表面为负、深部为正且缓慢增加的电位。在记录侧对侧小脑半球切除后，缓慢的运动前电位大小明显减小。有人提出，小脑半球（新小脑）在自主运动之前参与准备运动皮层的活动。
