a 109 region correlation matrix, as contrasted Threat > Safety. b Mean correlations (i.e., 4 A matrix columns collapsed) with SD lines in red. See Table 2 for regions above and below 1 SD from mean. c Ventral to dorsal axial slices of > ± 1 SD regions visualized on the brain: positive correlation regions red, negative correlation regions blue. d Thresholding in (b) and (c) was arbitrarily set at 1 SD; however, the observation that more regions were on average more positively connected during threat than safety is invariant to thresholding (red greater than blue line across thresholds: down arrow points to 1 SD point)
