Talaraich coordinates for the center of mass were derived from a random-effects group analysis. BOLD, blood oxygen level dependent. All contrasts were thresholded at a corrected threshold of P < 0.05, using an uncorrected P < 0.005 with a minimum cluster size of 2,360 mm3. For the joystick-targeting task, this resulted in extensive activation in bilateral frontal, parietal, and temporal cortex. To better clarify the anatomical regions activated by the pointing task, the pointing data reported in this table were rethresholded at a corrected P < 0.05 using an uncorrected P < 0.0001 with a cluster size of >333 mm3. Brodmann areas, where listed, are from the Juelich atlas (Eickhoff et al. 2005).
