Effects On ERP Derivatives🔗

VEP & FACE Tasks🔗

While the artifact is present at channel E55, it does not appear in the regions of interest (ROIs) for the VEP (left) and FACE (right) tasks, as illustrated for the Oz ROI for the subject data with artifact below:

MMN Task🔗

For the MMN task, the artifact does not appear in the T7/T8 ROI (left) because channel E55 is not used. However, the FCz cluster (right) includes electrodes E12 and E112, which may be affected by the artifact:
