EEG Correlates of the Afterimage of Visual Stimulation

Journal Article


Abstract


  • Occipital EEG alpha activity following visual stimuli of varying intensity was studied with particular reference to the visual afterimage. Subjects each received three stimuli of differing intensity under two conditions: with and without reporting of afterimage onset and offset required. A third condition controlled for possible reporting effects on the EEG. Findings indicate that visual afterimages are a significant determinant of the duration of EEG alpha desynchronization following visual stimulation and that where visual stimuli are employed the duration of EEG alpha blocking is unsuitable as an indicator of the OR to such stimulation.
