Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This phase will address long-term (3- and 6-month) neurobehavioral outcomes, including opioid relapse, craving, and sustained EEG changes during a paradigm that challenges networks associated with craving (CR) and cognitive control (CCN). During the 24 weeks of buprenorphine or methadone maintenance treatment, the investigators will examine our primary clinical outcome, relapse (opioid use on \>4 days per month and having an opioid positive urine screen), as well as days of opioid use.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
active tDCS
Each participant will undergo 5 consecutive (i.e., business days) sessions of active tDCS delivered to the DLPFC. During each session, participants are engaging in tasks that activate the cognitive control network.
active tDCS
The anode will be placed over the right DLPFC (F4 on the EEG 10-20 system) and the cathode over the left DLPFC65 (F3) using 25cm2 sponges at an intensity of 2mA. Stimulation will be delivered for 20 minutes via two saline-soaked surface sponge electrodes and a battery-driven, constant current stimulator (NeuroConn DC Stimulator Plus).
sham tDCS
Each participant will undergo 5 consecutive (i.e., business days) sessions of sham tDCS delivered to the DLPFC. During each session, participants are engaging in tasks that activate the cognitive control network.
sham tDCS
Same device and procedures as active tDCS with the exception that the device includes a study mode, in which subject-specific codes are entered to deliver active or sham stimulation, keeping the administrator blinded. Sham stimulation will use a method in which stimulation will be ramped up and back down over a 30-second period at the beginning and end of sham tDCS.
