[Acquisition and Forgetting of Memory in Motor Learning: Motor Memory with Multiple Timescales]

Examination of temporal patterns in adaptation and extinction in human motor learning suggests the presence of multiple motor memories with different timescales. In this study, a computational model derived from behavioral data was use to, explain the analysis of brain. The results indicated that each brain region activated during motor learning is related to different timescales in motor memory. They revealed dynamic processes in the brain where multiple regions participate in the acquisition of memory at different stages of learning even in a single motor task.
