Abstract
Seven subjects were tested in a prolonged (1-h 15-min) compensatory manual tracking task with monopolar EEG (01, C3, and FP1) and EOG recorded. Five of the seven subjects displayed a performance decrement between the first and the fifth 15-min periods of the task. For those five subjects, significant positive correlations were observed between performance and EEG activity at 01 in the 5.7- to 7.6-Hz frequency band. For the same subjects, performance was also inversely correlated with EEG activity at 01 in the high alpha band (9.6-11.5 Hz). Similar changes were observed in high-frequency activity at C3. A single significant correlation was observed between performance and EEG (3.8-5.7 Hz) at the frontal lead. This pattern is congruent with the hypothesis that EEG signs of activation are related to performance in a prolonged manual control task.
