Pointing and grasping in unilateral visual neglect: effect of on-line visual feedback in grasping.

abstract：:While natural speech does not possess the same degree of temporal regularity found in music, there is recent evidence to suggest that temporal regularity enhances speech processing. The aim of this experiment was to examine whether speech processing would be enhanced by the prior presentation of a rhythmical prime. We...
