Four-minute moving average time courses of glutamate concentration estimates. Each point represents the percent change from resting concentration (averaged over 4 min) for (a) healthy, (b) major depressive disorder, (c) schizophrenia groups, and (d) all the groups combined. Shaded areas indicate that the Stroop Task is being performed during that time. Error bars represent inter-individual standard error of the mean. HC, healthy control; MDD, major depressive disorder; SZ, schizophrenia.
