The resulting VEP waveform from the simulated VEP signal, data with the VEP signal added, and with a variety of artifact-reduction strategies. Excluding the simulated signal, all methods were processed using HAPPE’s line-noise reduction, filtering, segmentation, and baseline correction steps. The top row shows the waveform for clean (A) and artifact-added (B) data in the frontal ROI. The middle row shows the waveform for clean (C) and artifact-added (D) data in the temporal ROI. The bottom row shows the waveform for clean (E) and artifact-added (F) data in the occipital ROI.
