The National Institute of Neurological Disorders and Stroke (NINDS), intends to publish a reissue Notice of Funding Opportunity (NOFO) to solicit applications for innovative, interactive research to answer significant scientific questions that are important for the mission of NINDS, via a synergistic collaboration between outstanding scientists who might not otherwise collaborate. The program project grant is designed to support research in which the funding of several interdependent highly meritorious projects as a group offers significant scientific advantages over support of these same projects as individual research grants.. This Notice is being provided to allow potential applicants sufficient time to develop meaningful collaborations and responsive projects. The NOFO is expected to be published in April 2024 with an expected application due dates in May and September 2024. NINDS will not have any receipt dates after September 2024, thus ending the program. This NOFO will utilize the P01 activity code. Details of the planned NOFO are provided below.
