The investigation on EEG characteristic parameters change when executing cognitive ability tasks under centrifuge G acceleration

Beta wave energy ratio and TBR parameter can better reflect the changes of pilot's cognition under overload environment, and the joint research of multiple frequency bands and multiple parameters helps to find the parameters and indicators with the potential to become the physiological monitoring index of pilot's cognitive operation capacity under overload condition more quickly and better. This study lays a foundation and provides a reference for the follow-up selection of physiological monitoring index of a pilot's cognitive operation ability and the research of monitoring technology on cognitive operation ability under overload condition.
