Deep brain stimulation of the internal capsule enhances human cognitive control

To prevent response sets or habituation, trial sequence in each block was pseudo-randomized so that subjects never had more than two trials in a row that shared the same valence, interference level, or desired response finger. All subjects first completed an MSIT block, resting-state collection, and image assessment with their DBS on at its usual clinical settings (DBS ON). For time-domain analyses, we subtracted the mean of this window from all trials for that specific subject; for frequency-domain, we converted data to decibels (dB) relative to baseline.
