Significant causal interactions involving the anterior cingulate. Time-frequency plots of effective connectivity patterns (represented as t-statistics) for healthy controls (HC, left), individuals with chronic tic disorder (CTD, middle), and the between-group differences (right). Individuals with CTD exhibited greater effective connectivity (blue in difference plots) from the right precuneus to anterior cingulate cortex (ACC), as well as bidirectionally between the ACC and midcingulate cortex (MCC). The dashed line represents stimulus presentation at t = 0. L, left; R, right.
