Title Rapid Visual Assessment From Evoked Potentials: An Alternative to Computer Averaging
Creator Kupersmith, Mark J; Nelson, Jeremiah I; Seiple, William H
Subject Rapid Visual Assessment; Evoked Potentials; Computer Averaging Alternative
Description Computer averaging the visual evoked potential, either transient or steady state, retrieves the actual wave shape of discrete evoked responses. The retrieval process is based on building up the response through superimposition. Obviously it must be assumed that the many weak responses being summed together are identical. This assumption works well in practice, although in fact there are amplitude and wave shape variations. (Childers, Dovle, Brinck and Perry, 1972; genera] critique in Aunon, McGillem & Childers, 1981) for which sophisticated signal processing remedies are available (Senmoto and Childers,, 1972). Particularly for late components, one should be circumspect in viewing the output of an averager as a picture of the true and only possible evoked potential waveform.
