The Reorganization of Insular Subregions in Individuals with Below-Level Neuropathic Pain following Incomplete Spinal Cord Injury

Table 2

Intergroup differences of gray matter volume in insula subregions.

Insula-subareas	Groups			value	value
	ISCI-P (mm^3)	ISCI-N (mm^3)	HCs (mm^3)
L-dAI				0.786	0.462
L-PI				0.283	0.755
L-vAI				1.073	0.351
R-dAI				0.620	0.543
R-PI				1.047	0.360
R-vAI				0.584	0.562

Results are displayed as . L: left; R: right; dAI: dorsal anterior insula; PI: posterior insula; vAI: ventral anterior insula; ISCI-P: incomplete spinal cord injury with neuropathic pain; ISCI-N: incomplete spinal cord injury without neuropathic pain; HCs: healthy controls.
