In both groups, a significant positive functional connectivity was observed between NAcc and: prefrontal cortex (e.g., ventromedial prefrontal cortex [vmPFC]) and thalamus, as previously reported in adults (Di Martino et al., 2008). In ADHD-C, the connection between NAcc and portions of the prefrontal cortex was stronger than in controls (i.e. left anterior prefrontal cortex and vmPFC), as evidenced on the between-group difference map (Figure 1).
