BACS is a reliable and sensitive measure of cognitive function in schizophrenia. The BACS consists of items across six subtests: Verbal Memory, Digit Sequencing, Token Motor, Verbal Fluency, Symbol Coding, and Tower of London. The subtest scale scores were used to compute a composite BACS t-score of 50 (20) is the mean (standard deviation) of a relevant index population. Higher values indicate better performance. Bayesian normal linear model was used for analysis.
Blood-oxygen-level-dependent imaging, or BOLD-contrast imaging, is a method used in functional magnetic resonance imaging (fMRI) to observe different areas of the brain or other organs, which are found to be active at any given time. The MID task is a reward anticipation paradigm that robustly engages the VS, a key area associated with coding incentive reward. Dysfunctional processing of reward information is associated with motivational impairments in schizophrenia. Motivational impairment is a key aspect of negative symptoms, and has been associated with reduced activity in the VS. Any change in BOLD signal that comes in fMRI is reported.
