FIG. 3.

No history of previously diagnosed concussions (Hx mTBI) connectivity differences. Significant (p<0.01) differences in pre-game and post-game connectivity in No Hx mTBI subgroup. (A) Overall connectivity differences, with circles representing seed regions of interest, width of arrow representative of T-scores as well as directionality. Examples of significant increases in connectivity (color bar indicates the Z-score equivalent) in fMRI activation as reported for (B) orbitofrontal cortex and (C) left retrosplenial cingulate cortex.
