Figure 8

Event-related averages for congruent vs. baseline and incongruent vs. baseline: (a) event-related average (congruent); (b) event related average (congruent); (c) event-related average (incongruent); (d) event-related average (incongruent). (a) and (b) Indicate the typical haemodynamic response in the congruent condition (increase in HbO relative to a decrease in deoxy-HbO). The typical haemodynamic response was not always evident in the incongruent vs. baseline condition (c and d).
