Seed-correlation comparing connectivity between placebo and atomoxetine sessions in patients with Parkinson's disease. (a) The seed region in right inferior frontal gyrus (IFG) (in blue). (b and c) Altered connectivity between the right IFG and left dorsolateral prefrontal cortex (DLPFC) on atomoxetine compared with placebo interacted with the change in category fluency between these two sessions (in orange). Patients who improved on the verbal fluency task while on atomoxetine also demonstrated increased connectivity between these regions (p=0.001 uncorrected).
