Figure 2

Event-related responses (ERPs). At the top (a) electrophysiological responses elicited by HC (magenta) and LC (green) sentences before (SPP time window indicated in gray) and after (N400, in yellow) the onset (time 0) of critical words. SPP before and N400 after animal (blue, central, b) and tool words (red, bottom, c) are shown for HC and LC conditions. Current source density (CSD) maps for the SPP (gray window) and N400 (yellow window) latencies are reported along with their color scale. CSD maps provide an estimate of the cortical activity after removal of volume-conduction effects.
