Experiments on functional role of peripheral input to motor cortex during voluntary movements in the monkey.

abstract：:Human functional magnetic resonance imaging (fMRI) studies, as well as lesion, drug, and single-cell recording studies in animals, suggest that the striatum plays a key role in associating sensory events with rewarding actions, both by facilitating reward processing and prediction (i.e., reinforcement learning) and by...
