Figure 4.

Contrast between the different n‐back task classes for patients (N = 15). First line: 2‐back versus 1‐back; second line: 3‐back versus 2‐back, third line: 3‐back versus 1‐back. Positive t‐scores represent positive signal change; negative t‐scores represent negative signal change (P _cor < 0.01). Please note the relative lack of functional contrast in line b indicating little change of activation between the 2‐back and 3‐back tasks (also compare to line b in Fig. 6).
