Fig. 2.
Brain regions activated related to time effects during performance during a working memory task (i.e., PASAT). The right hemisphere is displayed on the left side. The image on the right displays averaged t-maps from subjects with ADHD with significant (p < 0.005) task-related activation in rCBF increasing in the right lenticular nucleus and left insula. The image on the left displays averaged t-maps from healthy control subjects. Note no significant activation in the basal ganglia for the healthy subjects.
