[The Role of the Cerebellum-Thalamus-Motor Cortex in Motor Learning].

In motor learning, movement-related error information are used to modify subsequent movements. During arm-reaching tasks, endpoint error information was input and retained until the following trial. However, whether this process involves LTD in the cerebellum or LTP in the cerebellar nucleus-thalamus-cerebral cortical pathway remains unclear. Analyzing the spatiotemporal characteristics of thalamic error signals is necessary to elucidate the mechanisms underlying sustained error information retention within the cerebellum-thalamus-cerebral cortex pathway.
