(A) The FC shared by both smartphone overuse (SM-scale) and depressive symptoms (CDI-2: SR total score). The FC between anterior cingulate cortex and right superior lateral occipital cortex demonstrates a positive correlation with both (B) smartphone overuse and (C) depressive symptoms. Similarly, the FC between the left supramarginal gyrus and left putamen is positively associated with both (D) smartphone overuse and (E) depressive symptoms.
