在恒定植入电极的情况下，在猕猴对侧手的自我调搏运动之前，运动皮质前肢区域记录到表面负的和深的正的、缓慢增加的电位。在记录的运动皮质对侧小脑半球消融后，慢运动前电位的大小明显减小。有人认为，小脑半球(新小脑)参与了运动皮质在自主运动前的活动准备。
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.
