Figure 2.

Percentage of signal change recorded in the right IFG (MNI = 51, 18, 6) across training sessions for experimental and control groups. Bars show means and error bars indicate mean ± 1.0 standard error (SE). A significant increase of the BOLD signal in the right IFG (r = 0.98, N = 4 training sessions, P = 0.01 one‐tailed, regression analysis) across sessions was detected for the experimental group only and suggests a learning effect. Differential activation in the ROI target for session 4 versus session 1 was observed for the experimental group only (two‐tailed paired t test, N = 7, P < 0.05).
