This initiative aims to support research projects that investigate the dynamic links between the maturation of brain circuits and behavioral outcomes during development in rodents and non-human primates, focusing on neurodevelopmental trajectories and innovative methodologies. The research is critical for understanding cognitive, affective, and social behaviors, with the potential to inform therapeutic interventions for mental health challenges. Eligible applicants include a wide range of institutions and organizations, with a maximum funding amount of $500,000 per application and a project period of up to five years.
