| Research Abstract |
The main objective of this study is to determine how chronic pain can induce changes in nerve activity in the ACC using proton MRS. The N-acetylaspartate (NAA), glutamate(Glu), and GABA levels in the regions were determined from the spectral peaks, using 3-tesla MR device equipped with an MRS analytical device. The NAA, Glu, and GABA levels were then compared between the patient and control groups.
The NAA and GABA levels in the ACC were significantly decreased in the chronic pain patient group compared to those in the control group. It was suggested that decreased inhibitory neurotransmission efficiency in the anterior cingulate gyrus is involved in the pathology of chronic pain.
