Attention Network Hypoconnectivity in Adults Diagnosed as Having Attention-Deficit/Hyperactivity Disorder in Childhood

To the Editor We thank Qi et al¹ for their contribution to this important discussion about research in attention-deficit/hyperactivity disorder (ADHD). We wish to use this opportunity to respond to the letter.

We apologize for the typo in the Montreal Neurological Institute coordinate in the text of our article.² The anterior cingulate cortex should be x = ±10, y = 35, and z = 2 rather than x = ±10, y = −35, and z = 2. However, the legend for Figure 1 is correct and may have been misunderstood by Qi et al¹: left anterior cingulate cortex (ACC) and right ACC refer to the left and right seed region of the affective network. As noted in the legend, “participants with attention-deficit/hyperactivity disorder displayed greater resting-state functional connectivity between the [ACC] and superior parietal and cerebellar areas than did the control subjects. A, Left ACC (x = 18, y = −50, z = 64). B, Right ACC (x = 34, y = −76, z = −30).”²
