FIG. 2.

(A) Group level differences between cocaine users and controls for the sensory motor cortex and the left frontal–parietal network. Group-level activation maps for cocaine users are shown in row 1. Group-level activation maps for healthy controls are in row 2, and the last row displays group-level difference between cocaine users and controls (cocaine users>controls) (p<0.05, FWE corrected). (B) Scatter plots between various cocaine use measures and connectivity strength within the sensory motor cortex (top row) and the left frontal–parietal network (bottom row). A significant correlation was observed between resting-state functional connectivity of the sensory motor cortex and cocaine use duration.
