1 Function BIRN Science

2 FBIRN Goals Develop multi-site functional neuroimaging tools. Develop the capability to analyze, as a single data set, data acquired from multiple sites using tools developed from multiple sites. Implications for clinical applications and FDA approvals in addition to research.

3 The FBIRN Aims Calibration: –Assess and correct for the major sources of multi-site variation Cognitive Tasks: –Develop robust protocols for multi-site fMRI studies Analysis: –Develop methods to analyze multi-site fMRI data Tools: –Develop a scalable IT application toolkit to support multi-site fMRI studies Dissemination: –Make the tools, procedures, and collected datasets widely available
