Final words. (Top) Grand-averaged ERPs recorded over centro-parietal sites in response to idiomatic and literal phrases. (Bottom) Coronal, axial and sagittal views of swLORETA inverse solution source performed on the difference wave obtained by subtracting ERPs to literal from ERPs to idiomatic sentences in the time window 400-450, corresponding to the peak of N400 response. Grid spacing = 5 mm; estimated SNR = 3.
