Table shows regions-of-interest of the index fingers center-of-mass locations in MNI coordinates. ROIs are spheres with radius of 6 mm and volume of approximately 900 mm3. Note that any participant whose MNI projection seemed to be outside cortex is bolded. *We were unable to position the participant’s hand adequately to the movement actuator, values imputed for response strength of the non-dominant hand.
