Altered inferior frontal function during error detection. a Group difference in activity in left inferior frontal gyrus (L IFG) (top). Greater activity correlated with improved SSRT in TD and replication groups (middle) but with greater inattentive and total symptom scores in ADHD (bottom). b Group difference in activity in right inferior frontal gyrus (R IFG) (top). Greater activity correlated with improved SSRT in TD and replication groups but with greater hyperactive symptoms in ADHD (peak correlation of SSRT (TD) in R IFG is 2mm from IFG boundary). Activation and correlation maps are whole brain corrected, and locations are given in Talairach coordinates, portrayed in radiological space (left = right)
