In trial N, subjects may select the certain decision (25 RUB with a probability of 100%) or the risky decision (50 RUB or 0 RUB with a probability of 50%) depending on decision to switch or repeat task sets from trial N-1. Figure represents trial in the reward switch = risk block. B, tACS montage. Active electrodes were placed on F3 and F4 electrode, representing left and right frontal area. Placement of the reference electrode was the ipsilateral deltoid for F3 and F4. Zachary Yaple et al. eNeuro 2017;4:ENEURO.0136-17.2017 ©2017 by Society for Neuroscience
