MEG-Derived Functional Tractography, Results for Normal and Concussed Cohorts
Measures of neuroelectric activity from each of 18 automatically identified white matter tracts were extracted from resting MEG recordings from a normative, n=588, and a chronic TBI, traumatic brain injury, n=63, cohort, 60 of whose TBIs were mild. Activity in the TBI cohort was significantly reduced compared with the norms for ten of the tracts, p < 10-6 for each. Significantly reduced activity (p < 10-3) was seen in more than one tract in seven mTBI individuals and one member of the normative cohort.
