Left panel: Amplitudes (mean ± standard error of the mean) of the N20–P25 somatosensory evoked potential (SSEP) component in 2 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 SSEP N20–P25 peak-to-peak amplitudes (mean ± standard error of the mean) before and after sham tDCS and real tDCS
