A, Behavioral task. spTMS or ppTMS was applied during most trials while subjects responded with their right hand (large cylinder stay trial shown in example). Either the large or small cylinder illuminated to initiate each trial. On stay trials the same cylinder remained illuminated throughout the trial. On switch trials, the illuminated cylinder switched from small-to-large or large-to-small when the subject's hand released the touch-bar. B, MNI coordinates for TMS targets. Circular symbols indicate individual subjects' stimulation locations in MNI152 space. Ellipsoids represent 95% confidence limits of the mean group stimulation location for each area [left M1: X= −36.5 ± 7.0 (mean ± SD), Y= −13.1 ± 6.9, Z = 64.2 ± 6.3; right PMv: X = 55.4 ± 4.0, Y = 14.7 ± 4.7, Z = 29.5 ± 4.6].
