What is it about?
The study identifies recurrent basal ganglia–cortical loops as a critical mechanism for reward-driven motor adaptation, advancing the understanding of how reinforcement learning is encoded and implemented in the brain. In particular, we show that loop circuits with strong feedback are required for proper motor learnig and adaptation.

Why is it important?
Advancing our fundamental understanding of the BG-cortical network motor function may ultimately lead to better treatment of motor deficits in neurological disorders.
Perspectives
This theoretical work will also provide an original framework to understand how neural dynamics unwinds in the basal ganglia, thalamus and cortex during movement, and how reinforcement learning may change the motor output.
