In this experiment an attempt was made to determine which of a number of neuroelectric variables best predict the amplitude of the average evoked potential (AEP). Several EEG parameters derived from period analysis and amplitude integration of the primary trace, as well as the amplitude and latencies of single sensory evoked potentials, were treated with a stepwise multiple regression procedure. The amplitudes of certain components of the AEP were tested against the battery of independent variables (predictors) as separate criteria. The results of these analyses revealed that the amplitude of the single EPs accounted for the greatest proportion of variance in the AEP (each component measured). These data suggest that the size of the AEP is not dependent on spontaneous EEG fluctuations.
