Fig. 2From: Anodal transcranial direct current stimulation over the left temporal pole restores normal visual evoked potential habituation in interictal migraineursLeft panel: Amplitudes (mean ± standard error of the mean) of the P1–N2 visual evoked potential (VEP) component in 6 sequential blocks of 100 recordings are shown before and after sham tDCS (upper panel) and real tDCS (lower panel). Right panel: The bar graph represents the habituation slope of VEP P1–N2 peak-to-peak amplitudes (mean ± standard error of the mean) before and after sham tDCS and real tDCSBack to article page
