groups at mid-centroparietal sites, ERP analysis was restricted to four medial-lateral electrode pairs despite the use of 28-channel EEG montage with an average reference. In contrast, familiarity (Know) old/new effects were observed for patients over frontal sites beyond 500 ms, but for controls over temporoparietal sites between 500 and 800 ms, leaving it unclear whether these condition differences indeed reflect early mid-frontal old/new effects (FN400) linked to item familiarity (e.g., Curran, 1999; Curran and Cleary, 2003).
