The National Institutes of Health (NIH) is inviting applications for the BRAIN Initiative, specifically targeting the optimization of instrumentation and device technologies for neural recording and modulation. This funding opportunity aims to refine technologies that have already demonstrated proof-of-concept, focusing on enhancing neuroscience research through innovative approaches that integrate multiple scientific disciplines. The initiative is crucial for developing new capabilities in network recording and circuit manipulation, linking neural activity to behavior, and addressing major challenges in understanding the central nervous system. NIH anticipates awarding 15-20 grants with a total funding of up to $10 million annually, and interested applicants must adhere to specific guidelines, including the Plan for Enhancing Diverse Perspectives (PEDP), with a submission deadline of January 20, 2026.
