| Abstract | The electro-oculogram (EOG) is commonly used to detect, reject and remove ocular artifacts (OAs) from the electroencephalogram (EEG). We present a new time-frequency analysis of OAs found in the EOG. Our results indicate that in some tasks and subjects, frequencies up to 181Hz exist. Based on these results, we propose a minimum sampling rate for EOG. In addition, since EOG measurements typically contain signals other than OAs (including underlying EEG), we propose an alternate measurement of OAs based on a video-based eye tracker, and suggest a minimum frame rate for the use of such devices |
