Structure and function are examined in the language network with DT-MRI and BOLD fMRI during a cognitive task. Activated cortical regions are identified and used to determine activation levels in each subject. Additionally, the regions are used to identify fiber tracts of interest. Canonical correlation analysis is used to identify correlations between functional activation and average fractional anisotropy in the fiber tracts. For each correlation found, the highest weightings are found for cortical regions and a tract that connects to that region.
