Motor Imagery in professional keyboard musicians.

<p>A: MoIm-related increases of regional activation in the group of 12 musicians, when compared to the ‘Judgm’ condition of listening while covertly commenting on the perceived music (P<0.05, cluster-level corrected for the entire brain volume, at voxel-level FWE P<0.05; k = 8). Results are rendered onto the surface of a standard anatomical brain volume (Montreal Neurological Institute, SPM 2005). B: Between-group results showing MoIm-related activation increases in musicians (n = 12), when compared to MoIm in the group of 12 controls (P<0.001, uncorrected; k = 8). Regions with activation increases are labeled by the plots that show the contrast estimates and 90% confidence interval for the effects of interest at the (x,y,z) co-ordinates of maximum condition-related activation and T-value. Effects are provided for musicians and controls during (1) MoIm while perceiving familiar music excerpts, (2) MoIm of unfamiliar music excerpts, (3) Judgm of familiar music excerpts, (4) Judgm of familiar music excerpts. Positive co-ordinate values refer to the distance (in mm) right (x), anterior (y) and superior (z) to the middle of the anterior commissure. L = left, R = right, Ctx = cortex, post. = posterior, sup. = superior.
