Attention to movement modulates activity in sensori-motor areas, including primary motor cortex.

abstract：:We investigated the role of additional perceptual information (finger touch) and additional mechanical support (hand grasp) on the anticipatory postural adjustments (APAs) associated with fast arm movements performed by standing subjects. The subjects performed fast, unilateral shoulder ante-flexion movements while st...
