Fig. 3From: Multimodal characterization of the semantic N400 response within a rapid evaluation brain vital sign frameworkERP results demonstrating differential processing of semantic congruence and incongruence. a–c Grand-averaged ERP waveforms at the Fz, Cz, and Pz electrode sites, respectively. Shaded regions denote windows of interest (300–500 ms). d Mean ERP amplitudes averaged over the windows of interest, calculated for each subject and presented as Mean ± SEM across subjects. *p < 0.05Back to article page
