A research on a type of motor control by the cerebellum

我们研究了小脑如何参与平滑运动指令的产生。为此，我们进行了手臂和眼睛运动的实验。结果，我们发现从小脑浦肯野细胞记录的简单的脉冲活动编码了手臂运动的动力学。结果支持小脑优化运动动力学的假设。对于眼球运动，我们通过大脑皮层记录的神经活动来估计眼球跳动的发生时间、方向和幅度。我们成功地计算了优化的运动命令来实现估计的眼球运动。

We investigated how the cerebellum contributes to the generation of smooth motor commands. For this purpose, we carried out experiments in arm and eye movements. As a result, we showed that simple spike activities recorded from Purkinje cells in the cerebellum encoded dynamics of the arm movements. The results support the hypothesis that the cerebellum optimizes dynamics of the movements. As for eye movements, we estimated onset times, directions and amplitudes of saccadic eye movements from the neural activities recorded from cerebral cortices. We were successful in calculating optimized motor commands to achieve the estimated eye movements.
