More clusters with changes in brain activation between time points during the 2-back task were identified in the non-HU control group than in the HU group. Clusters with higher predictive power of time points were identified using a classification accuracy threshold of > .65 and a cluster-size threshold of > 20. These clusters had larger differences in 2-back BOLD signals between time points. In the non-HU group, 27 clusters, with most larger clusters localizing in the posterior region, were identified. In the HU group, 7 clusters with only 2 larger clusters localizing in the frontal region were reported.
