Significant brain regions showing altered hypothalamus functional connectivity in mTBI patients with PTH compared with mTBI patients without PTH

Brain region	BA	Peak MNI coordinates x,y,z (mm)	t value	Voxels
L hypothalamus
R superior medial frontal gyrus	10	18,30,42	−3.8630	34
R middle frontal gyrus	9	39,24,42	−4.0160	22
R hypothalamus
R middle frontal gyrus	9	36,33,33	−4.3566	15

A corrected threshold of p<0.001 determined by Monte Carlo simulation was taken as measuring that there was significant difference between groups. BA Brodmann area; MNI Montreal Neurological Institute; L left; R right; mTBI mild traumatic brain injury; PTH post traumatic headache
