r Coefficients and clusters of correlation found using the measure of maintenance. (A) r Coefficients and cluster of correlation between the dorsomedial prefrontal cortex and the measure of maintenance in cocaine-dependent individuals without current psychiatric comorbidities. (B) r Coefficients and cluster of correlation between the dorsomedial prefrontal cortex and the measure of maintenance in cocaine-dependent individuals with comorbid personality disorders from Cluster B. (C) r Coefficients and cluster of correlation between the neostriatum and the measure of maintenance in cocaine-dependent individuals with comorbid personality disorders from Cluster C. (D) r Coefficients and cluster of correlation between the dorsomedial prefrontal cortex and the measure of maintenance in cocaine-dependent individuals with comorbid personality disorders from Cluster C. Results are overlaid on sagittal, coronal, and axial sections of a normalized brain, and the numbers correspond to the “x,” “y,” and “z” coordinates in MNI space.
