This concept supports the development of informatics tools for analyzing, visualizing, and integrating data related to the BRAIN Initiative to enhance our understanding of brain circuits. This concept is part of the ongoing development of an informatics infrastructure for the BRAIN Initiative. Other informatics programs include developing data standards that are needed to describe the new experiments created by or used in the BRAIN Initiative (RFA-MH-20-128) and creating the data infrastructures that would house the data from multiple experimental groups (RFA-MH-20-600).
