The National Institutes of Health (NIH) has announced a funding opportunity titled "Engineering Next-Generation Human Nervous System Microphysiological Systems (R21 Clinical Trials Not Allowed)," aimed at encouraging exploratory research to develop advanced microphysiological systems (MPS) that accurately replicate complex human nervous system architectures. This initiative seeks to facilitate studies on nervous system development, function, and aging, particularly in relation to neurological diseases. The R21 grant allows for a budget of up to $275,000 over two years, with applications opening on January 16, 2025, and a submission deadline of January 7, 2026. Interested applicants can find more information and guidelines at the NIH grants website or contact NIH Grants Information at grantsinfo@nih.gov for further inquiries.
