You will be required to attend 3 visits, each lasting between 2-3 hours. At each of these visits you will complete a number of mood questionnaires and two cognitive tasks, one of which will be done with EEG. These visits include a baseline test, 24-hour test, and a 16-week test. You will be asked to take a probiotic, or placebo, throughout the duration of the study.
