Figure 7.2 Experimental design A: Across experimental sessions, each participant received stimulation of the anterior prefrontal cortex, dorsolateral PFC, and premotor cortex. The order was counterbalanced between participants (indicated with black, grey and white thunderbolts). Stimulation site order was counterbalanced across participants. Vertical dashed lines indicate a break. B: The order (stimulation and baseline condition) in which a participant would always perform the tasks ( figure 7.3 ) was counterbalanced between participants. Values represent mean (SD) time in minutes (min) between the start of two runs and between cTBS administration and the start of the subsequent fMRI session. In addition, in the bottom panel the mean time (across participants and sessions) between cTBS and the start of the baseline session is specified. cTBS: continuous theta burst stimulation; transcranial magnetic stimulation (TMS).
