Fig. 5.

Contrast of neuropathic and nociceptive pain severities in participants with chronic SCI (n = 37). Contrast of both pain intensities identified A) differential connectivity between of the posterior cingulate cortex (PCC) and occipital cortex dependent upon pain type. Color bars indicate connectivity strength and correspond to greater connectivity associated with higher neuropathic pain and lower nociceptive pain intensities, with yellow indicating highest connectivity values. B) Scatter plot representing differences in connectivity alterations associated with neuropathic (red) and nociceptive (blue) pain intensities identified between the PCC to the occipital cortex. The shape of the data points delineates participant medication use defined as no pain medications (circle), gabapentin (square), opioids (triangle), or gabapentin and opioids (diamond).
