Abstract

A potential for detecting high gamma band (HGB) activity from scalp EEG is explored by employing a high input-impedance electroencephalograph for the measurement. An anti-saccade task was designed to elicit motor-related HGB activity. As a result, we confirmed increased power of HGB (100-105 Hz) preceding the anti-saccade initiation in all three subjects. A common timing of the power increase was observed at 50% point of mean reaction time of anti-saccade for each subject.
