Fig. 2: [11C]UCB-J distribution volume ratio (DVR) and levels of glutamate (Glu/Cr) in the anterior cingulate cortex (ACC).

Significant positive relationship between [11C]UCB-J DVR and Glu/Cr levels in the ACC in the healthy volunteer group (HV, rho = 0.55, p = 0.02), and no significant relationship in the schizophrenia group (SCZ, rho = 0.30, p = 0.18). Linear regression line shown.
