Recent evidence that the cerebellum is involved in perception and cognition challenges the prevailing view that its primary function is fine motor control. A new alternative hypothesis is that the lateral cerebellum is not activated by the control of movement per se, but is strongly engaged during the acquisition and discrimination of sensory information. Magnetic resonance imaging of the lateral cerebellar output (dentate) nucleus during passive and active sensory tasks confirmed this hypothesis. These findings suggest that the lateral cerebellum may be active during motor, perceptual, and cognitive performances specifically because of the requirement to process sensory data.
最近有证据表明小脑参与感知和认知,这对小脑主要功能是精细运动控制的主流观点提出了挑战。一种新的替代假说是,外侧小脑并非由运动本身的控制所激活,而是在获取和辨别感觉信息的过程中被强烈激活。在被动和主动感觉任务期间对外侧小脑输出(齿状)核进行的磁共振成像证实了这一假说。这些发现表明,外侧小脑在运动、感知和认知表现过程中可能处于活跃状态,具体原因是处理感觉数据的需要。
