Figure 4 - Positive associations were seen between glutamate in the anterior cingulate cortex (ACC) and A) n-acetyl-aspartate (NAA) (p<0.0001), B) n-acetyl-aspartate with n-acetyl-aspartyl-glutamate (NAA+NAAG) (p<0.001), and C) myo-inositol (mI) (p<0.0001) in the anterior cingulate cortex (ACC). D) Glutamate with glutamine (Glx) was positively associated with myo-inositol (mI) in the anterior cingulate cortex in the schizophrenia group (p<0.01).
