Electroencephalographic Correlates of Pilot Performance: Simulation and In-Flight Studies

Abstract : Both laboratory and in-flight studies were carried out in order to evaluate the utility and feasibility of EEG monitoring as a means of identifying central nervous system correlates of performance and G-force effects during military flight operations. Four studies were conducted, two with controlled laboratory simulation, and two in actual flight during military training missions. Data analysis focused on EEG power-spectral density characteristics and their temporal modulation, specifically in sensorimotor and visual cortical areas. Several consistent findings emerged. During competent performance, a highly unique discrepancy appeared between left and right hemispheres in central 8-15 Hz activity. This pattern disappeared as performance degraded. The temporal situations, power at frequencies below 8 Hz was progressively and non- specifically enhanced.
