The Utilizing Invasive Recording and Stimulating Opportunities in Humans to Advance Neural Circuitry Understanding of Mental Health Disorders (R21 Clinical Trial Optional) funding call from the National Institute of Mental Health (NIMH) supports invasive neural recording studies focused on mental health-relevant questions. Invasive neural recordings provide an unparalleled window into the human brain to explore the neural circuitry and neural dynamics underlying complex moods, emotions, cognitive functions, and behaviors with high spatial and temporal resolution. This R21 funding supports shorter, higher-risk applications.
Applications are open to researchers at research institutions in the USA and worldwide.
The grant provides 275,000 USD for 2 years (plus indirect costs).
Funding opportunity number: PAR-25-291
Applications are due on June 16, 2026.
