The National Institutes of Health (NIH) is offering a funding opportunity titled "New Approaches for Measuring Brain Changes Across Longer Timespans" under the R01 Clinical Trial Optional grant program. This initiative aims to support multidisciplinary research that develops innovative methods for measuring brain activity and its relationship with aging and health outcomes over extended periods, focusing on both human and animal models. The program emphasizes the importance of tracking neurological changes over time and requires applicants to include a Plan for Enhancing Diverse Perspectives (PEDP) to promote inclusivity in research participation. Applications are due by May 7, 2027, with a maximum funding period of five years, and interested parties can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
