Panel (A) depicts the 53 intrinsic connectivity networks (ICN) derived across both mild traumatic brain injury (mTBI) patients and healthy controls (HC) following group independent component analysis. Individual ICN are clustered into seven over-arching networks: sub-cortical (SC; 6 ICN); default-mode (DM; 10 ICN); sensorimotor (SM; 8 ICN); visual (VS; 10 ICN); auditory (AD; 3 ICN); cerebellum (CB; 2 ICN); and cognitive control (CC; 14 ICN). Sagittal (X), coronal (Y) and axial (Z) slice locations are presented according to the Montreal Neurological Institute system. The color-coding for each ICN within each of the seven major networks is presented within Panel (B), as well as t-statistics representing the pair-wise comparisons of static resting state functional connectivity comparisons across the two groups. Individual ICN labels include: L, left; R, right; pDMN, posterior default mode network; MeFG, medial frontal gyrus; SFG, superior frontal gyrus; PCC, posterior cingulate cortex; ACC, anterior cingulate cortex; AG, angular gyrus; MFG, middle frontal gyrus; IPL, inferior parietal lobule; PHG, parahippocampal gyrus; IFG, inferior frontal gyrus; aInsula, anterior insula; CC, cingulate cortex; pre-SMA, pre-supplementary motor area; SPL, superior parietal lobule; PreCG, precentral gyrus; PoCG, postcentral gyrus; SMA, supplementary motor area; PCL, paracentral lobule; STG, superior temporal gyrus; MTG, middle temporal gyrus; pInsula, posterior insula; FFG, fusiform gyrus; LG, lingual gyrus; MOG, middle occipital gyrus; SOG, superior occipital gyrus; IOG, inferior occipital gyrus. A priori hypothesis examined the DM and SC networks. Panels (C) and (D) present the pair-wise Pearson correlation values (r) for HC and mTBI patients, respectively.
