During this task participants will receive simultaneous EEG/TMS, while they engage in the virtual T-maze decision making task, used in our previous reward positivity studies on SUDs. ERPs will be recorded throughout the T-Maze task, and the reward positivity will be measured as the difference in maximum amplitude between reward and no-reward feedback conditions.\n\nThe TMS coil will be positioned using a an Adept Viper s850 robotic arm (SmartMove, ANT Neuro, Enschede, The Netherlands), providing precise targeting of the predetermined left dorsolateral prefrontal (DLPFC) coordinate (\\< 10 mm from the scalp, orientated at a 45º angle).
