Abstract

The change of the viewed evoked potential (VEP) waveforms when the stimulus changes gradually from a random pattern to an ordered pattern is addressed using the ALOPEX process. For this purpose a sequence of patterned stimuli are generated by ALOPEX where the response function is simulated in such a way as to obtain convergence in a known geometrical pattern. Peak N2 (135-170 ms) seems to be affected maximally by this convergence. The reverse experiments were also conducted with exactly the opposite effects on N2. N2 latency and/or amplitude or the complex P1-N2-P2 are mainly affected by the transition from order to disorder.
