What the grant funds
The Joint NINDS/NIMH Exploratory Neuroscience Research Grant program supports exploratory and innovative research projects, which fall within the missions of the NINDS and NIMH. Awards will provide support for the early and conceptual stages of projects. These studies often assess the feasibility of a novel avenue of investigation and involve considerable risk, but have the potential to bring about breakthroughs in the understanding of important areas of neuroscience, or to the development of novel techniques, agents, methodologies, or models, of high value to the neuroscience community. While this funding opportunity also accepts clinical trials, only applications proposing mechanistic clinical trials or studies or basic experimental studies with humans (BESH) will be considered for funding. For information on the types of clinical trial that are within scope of this funding opportunity announcement, refer to Funding Opportunity Description, below.
