Combining Neuro-Imaging and Non-Invasive Brain Stimulation for Clinical Intervention in Opioid Use Disorder

The overarching goal of this project is to expand the traditional expertise in non-invasive neuromodulation at the University of Minnesota towards developing novel paired-neuromodulation approaches using transcrancial direct current stimulation (tDCS) for new addiction treatments that support long-term abstinence. This study will investigate whether the pairing of dorsolateral prefrontal cortex (DLPFC) stimulation and cognitive training can enhance functional connectivity between DLPFC and nucleus accumbens (NAcc). We have identified higher functional connectivity between DLPFC and NAcc in alcoholics that have successfully maintained abstinence for extended periods of time (7 years). This paired-neuromodulation approach can potentially be used as a therapeutic intervention to decrease substance use probability in addiction (e.g. opioid use disorder). The long term goal is to develop new addiction treatments that support long-term abstinence in opioid use disorder. The overall objective of this proposal is to enhance functional connectivity between DLPFC and NAcc as a therapeutic intervention to enhance cognition and reduce substance use rates in opioid use disorder.
