Inter-individual differences in GABA concentration can shed light on the role of inhibition in cognitive processes. To date, several studies have shown that GABA concentration in functionally unrelated regions does not correlate between individuals. In this study we test the hypothesis that GABA concentration in two functionally related regions, right and left sensorimotor cortex, correlates across individuals.
