↵F8-150 With a priori an anatomical constraint that the right PMd with Talairach’s coordinates of x = 20, y = −10, z = 52, and x = 22,y = −10, z = 52, specified by the (parallel–mirror) comparison of bimanual sequential finger movements in Experiment 1, and its surrounding regions, which fall within the FWHM of the SPM(Z), are the regions of interest. A Bonferroni correction for the two locations was applied.
