Table 3 Word Generation Task change in the BOLD signal for each region of interest pre-post lithium The change in each region of interest is shown for the working memory task (mean ± SEM). There are three treatment groups: healthy controls, euthymic bipolar patients, and depressed bipolar patients. Significant differences (and trends towards significant differences) between patient group and controls are shown as are significant differences (and trends towards significant differences) between euthymic bipolar patients and depressed bipolar patients.
