Abstract
Although VEP (visual evoked potential) is an electrophysiological test commonly used in investigating different neurophysiological disorders, there are not many objective criteria for distinguishing a normal from an abnormal VEP. The authors used the phase characteristics of the power spectrum for the distinction of VEPs. The phase spectrum of a VEP was proved to have a certain periodicity in the 0-40-Hz region. By studying the phase characteristics of VEP waveforms, the authors were able to determine the range of the period that characterizes normal and abnormal VEPs and to establish an experimental method for distinguishing the different populations.<>
