The National Institutes of Health (NIH) is inviting applications for the BRAIN Initiative, specifically targeting the optimization of instrumentation and device technologies for recording and modulation in the nervous system. This funding opportunity aims to enhance the understanding of neural circuits by supporting projects that utilize innovative technologies, such as optical, electrical, magnetic, or acoustic methodologies, to address significant challenges in neuroscience research. Successful proposals should demonstrate a commitment to interdisciplinary collaboration and include a Plan for Enhancing Diverse Perspectives (PEDP) to foster inclusivity among diverse teams and institutions. The initiative anticipates awarding approximately $10 million across 15-20 projects, with applications due by January 20, 2026.
