Figure 5. Overview of the ERP effects in the post bump event epoch.

Figure 5

A) Grand average waveforms of the central midline electrode (Cz) displaying the P2 bump group effect (patients>controls; also reflected in the topography) and the P2 bump linguistic condition or lexical access effect (‘W’ = ‘S’<‘C’) within the time window 180–280 ms post bump event. B) Grand averages of the fronto-central midline electrode (FCz) reflecting the P3 bump syntactic complexity effect (‘S’>‘W’; reflected in the dark grey fill in the ERPs and in the corresponding topographies) and the P3 group effect (patients>controls; see also topography) within time window 300–500 ms post bump event.
