Effects of Transcranial Electrical Stimulation on Task Performance in Healthy Adults

Active tES delivered using the Soterix Medical MXN-33 HD-tES stimulator. Stimulation is applied via high definition electrodes targeting either the left DLPFC or L-aINS at intensities up to 1.9 mA. Stimulation is performed for up to 45 minutes during task execution. Participants perform the ROBoT-r task during stimulation.

Sham tES using the same Soterix Medical MXN-33 HD-tES stimulator and electrode placements. Stimulation ramps up and down over 20 seconds to mimic sensation but provides no continuous current. Participants perform the ROBoT-R task under sham conditions.
