The National Institutes of Health (NIH) is offering a funding opportunity titled "Mechanistic Research on Neuromodulation for Substance Use Disorders Treatment," aimed at encouraging clinical research to identify novel targets for non-invasive brain stimulation (NIBS) relevant to substance use disorders (SUD). This initiative seeks applications that propose mechanistic studies involving Basic Experimental Studies with Humans (BESH) to understand neurobiological, cognitive, and behavioral responses to NIBS, which are essential for advancing treatment strategies for SUD. The NIH plans to allocate approximately $1.5 million across fiscal years 2024 to 2026 for up to six awards, with a submission opening on December 16, 2023, and a closing date of August 14, 2026. Interested applicants must include a Plan for Enhancing Diverse Perspectives (PEDP) in their proposals and can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
