tDCS and the Gaze Cueing Effect

Influence of Transcranial Direct Current Stimulation Applied to the Right Orbitofrontal Cortex on Gaze and Arrow Cueing Effects

This study employs transcranial direct current stimulation (tDCS) to investigate the role of the orbitofrontal cortex (OFC) in processing gaze and arrow cues.

This study employs transcranial direct current stimulation (tDCS) to investigate the role of the orbitofrontal cortex (OFC) in processing gaze and arrow cues.To examine the distinct functions of the OFC in processing social versus non-social stimuli, participants were randomly assigned to one of three tDCS groups: anodal, cathodal, or sham. Following stimulation, all participants completed a spatial cueing task involving both gaze and arrow cues. Two stimulus onset asynchrony (SOA) conditions (200 ms and 600 ms) were implemented to investigate how timing modulates the processing of these cues within the rOFC.
