Table 2. Tissue characteristics are closely associated with fear-related behaviors.

Local tissue characteristics of LA, BLA, CeA, and mPFC are correlated with changes in fear-related behavior with different patterns of correlation in CD and WD groups. FA and T2 measures for amygdala and mPFC were significantly correlated with fear extinction in CD group (L LA FA: p = .029; R LA FA: p = .017; L BLA FA: p = .015; L BLA T2: p = .021; R CeA T2: p = .022; L mPFC FA: p = .0095). Diffusivity scalars (MD and RD) of the left CeA showed a robust significant correlation with fear learning in the control rats only (L CeA MD: p = .017; L CeA RD: p = .0043). Note that these associations were nonexistent in the WD group. *p < 0.05.

Note: R² values above a threshold (R²>0.6) are shown;

^*p < 0.05,

^#p < 0.1
