Selective attention modulates visual and haptic repetition priming: effects in aging and Alzheimer's disease.

abstract：:Although it is well known that the corticospinal system exerts more influence over distal (hand and fingers) than proximal (elbow and shoulder) upper limb muscles, differences in the importance of this system for voluntary activation of these muscle groups have not been demonstrated directly. Two investigations were c...
