Results are displayed as mean ± standard deviation. 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.
