Parietal–premotor cortical areas engaged during the hand-selection phase. A, Common activations in all trial types averaged across participants rendered on a single-subject standardized brain template in SPM2 viewed from a dorsal aspect (render depth, 20 mm; L, left; R, right; A, anterior; P, posterior). B, Common mesial frontal cortex activation shown on a sagittal slice of the brain obtained as described in the legend of Figure 3C. The vertical line indicates the position of the vertical plane passing through the anterior commissure. The depicted cluster involved both the superior frontal gyrus (BA 6; local maximum at −4, −4, 58) and the middle cingulate gyrus (BA 24; −4, 6, 36).
