Outcome parameters: Two main comparisons are of interest. First, baseline differences in neural and cardiac measures between CD and HC participants will be identified. CD participants are expected to show dysregulations in these functions, relative to HC participants. Second, neural plasticity related to these functions due to iTBS treatment and reduction in cocaine use will be measured. The active-iTBS intervention is expected to be effective in reducing cocaine use, relative to the sham-iTBS intervention. Normalization of circuit dysregulation is hypothesized to be associated with reduction of cocaine use. Overall, the current protocol is designed to test whether iTBS to left dlPFC is efficacious in reducing cocaine use.
