Example of tele-monitored tDCS (tele-tDCS) setup including the tDCS device (for at-home sessions), head strap and the videoconferencing platform. The depicted tDCS device is a Soterix Mini-CT tDCS. The device delivers direct electrical current through saline-soaked sponge electrodes (5 cm × 5 cm) snapped to a custom-made head strap. The head strap has clear labeling for reliable electrode placement (right picture). This configuration provided a uniform bi-hemispheric dorsolateral prefrontal cortex montage centered using a nasion marker. The supervising study technician is shown in the laptop screen (left picture) as a study participant would see it during video-conferencing
