Fig. 2From: Habituation of laser-evoked potentials by migraine phase: a blinded longitudinal studyGrand average of the LEP-traces in first session interictal recordings and controls. N2P2-habituation was present in both groups, but we found no significant N1-habituation. The amplitudes in the figures are smaller than those presented in Table 4 due to slightly different LEP-latencies between participantsBack to article page
