Pre-trauma functional connectivity correlated to differential fear responses. a Correlations between pre-trauma RSFC and freezing time for all connections (upper triangle) and super-threshold connections (lower triangle, each white element represents a supra-threshold connection). Brain regions are arranged based on the brain system (color coded) they belong to. b Three representative RSFC maps, generated with ACC, AON, and PBn as the seed, respectively (colored voxels, p < 0.05, FDR corrected). Distance to Bregma was labeled at the top of each slice. ACC, anterior cingulate cortex; AON, anterior olfactory nucleus; HT, hypothalamus; nLOT, lateral olfactory tract nucleus; PBn, parabrachial nucleus
