When applicable, values are median (interquartile range). Combined p values are uncorrected (although GABA represents a primary hypothesis) and are based on Friedman's test, treating hemisphere as a blocking variable. Where these are significant, p values are shown for the LAC and RAC, which are based on Wilcoxon's rank-sum tests. Significant group differences are shown in bold.
