All regions/clusters are significant at P<0.05, corrected for multiple comparisons within a priori sensorimotor and ventrolateral premotor cortex ROIs (see Methods section). All cluster sizes <50 voxels. The direction of the correlation (+ or −) is given next to the value for the coefficient of determination, r2.
C = contralateral, I = ipsilateral to hand movement, BA=Brodmann area, BG=parameter estimate for the main effect of hand grip, BF=parameter estimate for the force covariate (see Methods section).
