Group level trigeminal and olfactory ERP in MWA and MWoA, in left or right nostrils. The stimulus onset is positioned at 0 s (dotted black line). Signals were taken from the Pz electrode. Bold blue line: MWA; Dotted red line: MWoA. Choc: Chocolate, L: left, R: right. Significant differences in peaks amplitudes between aura and without aura groups were found with CO2L for P3 and N1P3 and with the chocolate odor for P2 and P3 (two-tailed unpaired t-test P < 0.05, MWA > MWoA)
