Inhibitory tone is regulated differently in men with and without autism spectrum disorder (ASD). The change in inhibitory index was negatively correlated with changes in Glx in controls (Pearson correlation; r=−0.705, P<0.01), but not men with ASD (r=0.357, P=0.28). Furthermore, there was a significant group difference in correlation coefficient (Fisher r to z transform, z=2.23, P<0.01). Results are expressed as z-scores ((value−mean)/standard deviation) and are corrected for State anxiety score.
