Areas of Significantly Increased or Decreased Activation for IPV-PTSD vs. Controls for Matching to a Fearful vs. Happy Target Face

Analysis	Side	Anatomical Area	Size (μl)	X	Y	Z	Voxelwise Statistics: Mean (SD)
							F*	p*
ROI	L	Insula (a)	448	-41.4	8.0	-4.6	6.035 (1.68)	.028 (.016)

WB	B	Brainstem	2304	-3.5	-34.4	-36.2	7.439 (3.81)	.025 (.018)
WB	L	Middle Frontal Gyrus	896	-44.7	16.9	29.9	7.250 (2.87)	.023 (.019)
WB	L	Precentral Gyrus	896	-44.2	-7.1	37.9	6.698 (2.34)	.024 (.017)
WB	R	Middle Temporal Gyrus (-)	832	45.7	-71.0	14.2	8.307 (4.03)	.016 (.012)

Cluster coordinates and anatomical areas are for cluster center of mass as defined by Talairach stereotactic space; Negative (-) signs following anatomical area indicate reduced activation; Descriptors for insula clusters do not reflect stereotactic distinctions, but are estimates based upon the relative location of activation on the group map

^*Voxelwise statistics are presented with education covaried out; ROI=region of interest; WB=whole brain; a=anterior insula.
