Upper panel: regions showing main effects of estimated volatility-related activation during the decision phase, a subset of which display contrast-masked group differences (controls > CHR; bold text); Lower panel, in italics: additional regions showing controls > CHR differences, identified using whole-brain correction; R = right and L = left hemisphere.
