Experimental design. (A) and (B) Stimulation sites over the left, right and bilateral pIFG and aIFG; respectively. Mean MNI-coordinates were obtained from previous studies (Devlin et al., 2003; Gitelman et al., 2005; Gough et al., 2005; McDermott et al., 2003). ant = anterior, post = posterior, l = left, r = right. (C) Auditory and visual run of the two blocked tasks. (D) Single trial: each trial had a duration of 3000 ms. A 4-pulse train of 10 Hz online TMS was applied 100 ms after word onset over left, right or bilateral aIFG or pIFG. Subjects responded with their left index or middle finger. ms = milliseconds; min = minutes.
