TMS manipulation experiment. (A) Behavioral paradigm. A single-pulse TMS was given at variable timing between visual stimulus onset and behavioral response. Trials in which TMS was given within the time window between 30 and 400 ms before behavioral response were analyzed. (B) Stimulation sites rendered on a template MNI brain. Dorsal and ventral clusters indicate FEF and PFv stimulation sites, respectively. Color bar indicates the number of overlapped subjects. Note that the number of subjects was 20 and 13 for FEF and PFv stimulation, respectively. (C) TMS effects on behavior. Accuracy (top) and RT (bottom) for each motion coherence level (abscissa) are shown separately for FEF (left) and PFv stimulation (right).
