We have explored resting state functional connectivity in asymptomatic high school American football players and a cohort of non-contact athletes peers. Seed-based default mode network (DMN) analysis reveals that while the total number of voxels included in the DMN did not change significantly with hits, the location of the DMN, as defined by number of voxels in MarsBaR regions, did. Independent component analysis (ICA) on all sessions was used to find stable networks. Pairwise correlations between networks were significantly different in players than controls in 8 of the 15 pairs, and further were correlated with hits in some cases.
