Cingulate GABA levels inversely correlate with the intensity of ongoing chronic knee osteoarthritis pain

Conclusion Our study supports mid-anterior cingulate cortex -aminobutyric acid as a potential marker of pain severity in chronic nociceptive pain states independent of negative affect. The findings suggest that GABAergic disinhibition of the salience network may underlie sensitization to averse stimuli as a mechanism contributing to pain chronification.
