Role of latency jittering correction in motion-onset VEP amplitude decay during prolonged visual stimulation
Original language description
Visual evoked potentials to motion-onset stimulation (M-VEPs) gradually attenuate in amplitude during examination. The observed decline in averaged responses can be caused by decreases in single response magnitudes and/or increased variability in a response delays, i.e., latency jittering. To illuminate the origins of the suppression of M-VEPs during stimuli repetition we used correlation technique to estimate an upper bound of possible latency jittering of single sweeps and we evaluated the effect of its correction on the amplitudes of three M-VEP dominant peaks P1, N2 and P3. During prolonged visual motion stimulation, the variability of corrective latency shifts in the occipital region increased (r = 0.35 : 0.44) and the number of single responses corresponding to the average curve declined in occipital and parietal derivations (r = -0.48 : -0.62). While the P1 peak amplitude did not exhibit any time-specific behaviour, the N2 amplitude exhibited a significant decay of 29.4 % that w
