[The evaluation of the effect of variable latency periods on the averaged evoked potential].

The data on averaged EPs were used for simulation of stationary responses to sensory stimuli. The EP variability was observed when the range of the latency shift exceeded 90 msec. The N1, P2 and N2 components of the averaged long-latency auditory EPs were chosen for estimation of the latent variation range in normal subjects using encephaloscopy (RES) technique. The variability of the averaged EP was shown to depend on the difference among the component ranges, particularly N1 and N2 those. The advantages of the proposed RES technique for investigation of the EP variability and the possibilities of the estimation of non-stationary responses to sensory stimuli, are discussed.
