With chronically implanted electrodes, surface and depth potentials of the premotor and motor cortices were recorded on hand movements in response to a visual stimulus in monkeys, and influences of cerebellar hemispherectomy were examined upon visually initiated premovement cortical potentials. Early, surface positive--depth negative premovement potentials emerged in the cortices on both sides, and following surface negative--depth positive premovement potentials appeared in the motor cortex contralateral to the moving hand. Cerebellar hemispherectomy contralateral to the motor cortex eliminated the following potentials. This suggests the participation of the neocerebellum in preparing the motor cortex for visually initiated movements.
使用长期植入电极，记录了猴子在视觉刺激下手部运动时运动前区和运动皮质的表面及深部电位，并研究了小脑半球切除术对视觉引发的运动前皮质电位的影响。早期，两侧皮质均出现表面正向——深部负向的运动前电位，随后，在与运动手对侧的运动皮质中出现表面负向——深部正向的运动前电位。与运动皮质对侧的小脑半球切除术消除了后续电位。这表明新小脑参与为视觉引发的运动准备运动皮质。
