Table 1 Subjective ratings of perceived intensities, N1 and N2–P2 amplitudes, as well as ‘ERP’ and ‘α-ERD’ magnitudes elicited by nociceptive somatosensory (LEP), non-nociceptive somatosensory (SEP), auditory (AEP), and visual (VEP) stimuli that were delivered to the left and right sides (data are expressed as mean ± SEM).
