The National Institutes of Health (NIH) is announcing a funding opportunity titled "BRAIN Initiative: Theories, Models and Methods for Analysis of Complex Data from the Brain," aimed at supporting research that develops computational tools for understanding dynamic brain circuits. This initiative encourages small businesses to create and disseminate theories, models, and methods that enhance the analysis of neural circuit mechanisms and functions, with a focus on collaborative investigations that integrate mechanistic and predictive models of neural dynamics. The estimated total program funding is $6 million, with applications expected to be solicited in the future; interested parties should prepare for submission by considering potential collaborations. For further inquiries, contact Jessica Mollick, PhD, at 301-827-2949 or via email at Jessica.mollick@nih.gov.
