Signal Analysis Techniques for Interpreting Electroencephalograms

Abstract

The principal objective of this study was to review and assemble the relevant signal processing literature for analyzing and interpreting EEG, especially steady-state visual evoked responses (VER). The principal Air Force objective is to investigate the usefulness of the VER as a tool in assessing the effects of visual stimuli upon the flier, especially stimuli which could lead to a temporary (or permanent) degradation of performance. This could include flashblindness, disorientation, or other physiological impairment caused by visual stimuli. The study concentrated on those methods suitable for analysis of the spontaneous EEG. However, methods of modeling the spontaneous EEG have been considered, since by eliminating spontaneous EEG components, the VER should be more evident. The problem of measurement variability observed after signal processing was investigated, and a thorough literature search was conducted to look for neurophysiological evidence of variability and possible cures.
