Highlights

Dynamic reorganization of striatal circuits during the acquisition and consolidation of a skill. by Henry H
Since the striatum is essential for motor skill learning, the findings that the dorsomedial striatum (DMS) and dorsolateral striatum (DLS) are important for rewardguided instrumental learning raises the question whether the DMS and DLS play similar roles in the fast and slow phases of motor skill learning
The authors found that lesions of the DMS impaired skill learning only in the early phase, similar to the effect of DMS lesions in reward-guided instrumental learning

Summary

Introduction

Dynamic reorganization of striatal circuits during the acquisition and consolidation of a skill. by Henry H. The initial phase of rewardguided instrumental learning is deliberate and sensitive to both the action-outcome contingency and the value of the outcome. Two subregions of the striatum, the dorsomedial striatum (DMS) and the dorsolateral striatum (DLS), have been shown to play crucial roles in the learning of goal-directed actions and habit, respectively.
