(A) Pearson correlations for mean fractional anisotropy of overlapping white matter voxels identified for each ROI pair (i.e. Motor ∩ mPFC; mPFC ∩ Ins; Motor ∩ Ins)

		% Sig change difference during ACA
		Motor − mPFC (r, p)	mPFC − Ins (r, p)	Motor – Ins (r, p)
Mean FA	Motor ∩ mPFC	−0.08, 0.81	0.114, 0.74	−0.002, 0.99
	mPFC ∩ Ins	0.53, 0.09	−0.102, 0.77	0.72, 0.012
	Motor ∩ Ins	0.05, 0.88	−0.03, 0.94	0.06, 0.87

		% Sig change during ACA
		mPFC	Insula	Motor
Mean FA	mPFC ∩ Ins	−0.098, 0.77	0.038, 0.91	0.675, 0.023
		CTQ Scores

% signal change difference for the same ROI pair during the anticipation of certain aversion (ACA); (B) the significant mPFC‐Ins pair and the % signal change in each region of the mPFC, insula and motor cortex; (C) the significant mPFC‐Ins pair and CTQ scores.

Significant correlations are highlighted in bold

FA = mean fractional anisotropy; p = p‐values; r = Pearson's correlations.
