From: Anodal transcranial direct current stimulation over the left temporal pole restores normal visual evoked potential habituation in interictal migraineurs

Fig. 1

Left panel: Amplitudes (mean ± standard error of the mean) of the N1–P1 visual evoked potential (VEP) component in 6 sequential blocks of 100 recordings are shown before and after sham tDCS (upper panel) and anodal tDCS (lower panel). Right panel: The bar graph represents the habituation slope of VEP N1–P1 peak-to-peak amplitudes (mean ± standard error of the mean) before and after sham tDCS and real tDCS. The arrow highlights interictal VEP habituation that was reduced before real tDCS but normalized after. ** = p < 0.01 before vs. after the intervention
