Table 3. Fear circuitry microstructural characteristics correlate with FPS responses.

The radial diffusivity (RD) for left mPFC tracts was significantly correlated with both fear extinction and fear learning in CD rats (Extinction: p* = .0280; Learning: *p = .025). Notably, no significant correlations were shown between right mPFC tracts or tracts connecting the mPFC to the BLA and fear-potentiated startle (FPS) responses.

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

^*p < 0.05,

^#p < 0.1
