Attention to speed of motion, speed discrimination, and task difficulty: an fMRI study.

abstract：:To gain efficiency in performance of a novel complex movement, we must learn to coordinate the action of the pertinent muscle groups. We used functional magnetic resonance imaging (fMRI) to investigate the mechanisms of learning a novel synergic movement in human primary motor cortex (M1). We show for the first time c...
