Population: Number of voxels that showed significant change in connectivity following administration of olanzapine.

Change in resting state functional connectivity to the medial prefrontal cortex and superior parietal lobules following olanzapine administration period. Whole-brain, seed-to-voxel analyses were conducted utilizing anatomically-defined seed regions and age-corrected within-subjects f-tests were run to determine the presence and size (in voxels) of clusters where connectivity changed significantly following olanzapine administration. Results are reported in units of voxels for each cluster meeting a threshold of voxel-level uncorrected p\<.001 and cluster-level p-FDR\<.05. A result of zero indicates that no clusters were identified within subjects as changed in connectivity relative to the seed regions.

Change in the MATRICS Cognitive Consensus Battery (MCCB), that includes 10 tasks that measure processing speed (Brief Assessment of Cognition in Schizophrenia - Symbol Coding, Animal Fluency, Trails A), attention (Continuous Performance Test), working memory (WMS-III Spatial Span, Letter-Number Span), verbal learning (Hopkins Verbal Learning Test - Revised), visual learning (Brief Visuospatial Memory Test - Revised), problem solving (Neuropsychological Assessment Battery Mazes) and social cognition (Mayer-Salovey-Caruso Emotional Intelligence Test). Scores from each subtest are normed and their T-scores are summed to yield a MCCB composite score, then the total composite T-score is standardized to normative data among a healthy population. The composite T-score has a mean of 50 and a standard deviation of 10. Higher total composite scores indicate better cognitive outcomes.

Change in Wisconsin Schizotypy Scales (WSS) Short Form score, a self-report questionnaire assessing schizotypy in clinical and non-clinical samples. The measure has four scales, each with 15 True/False questions. There are 13 red-herring questions, that, if answered "True" invalidate the test. Each "false" response is scored 0, and each "true" response is scored 1. Scores for each scale range from 0 - 15, with higher scores indicating greater schizotypy. The WSS positive schizotypy score consists of the summed score of the perceptual aberration and magical ideation scales and scores range from 0-30, with higher scores indicating greater positive schizotypy. The WSS negative schizotypy score sums scores from the physical anhedonia and social anhedonia scales and ranges from 0-30, with higher scores indicating greater negative schizotypy.

Changes in the Symptoms Checklist - 90 - Revised scale, which measures 9 domains of psychological dysfunction, summing to create an overall psychological distress (Global Severity Score). The scores of each of the 9 domains - somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism - combine for a total of 90 items, each measured on a 5-point scale. The sums of all 90 item scores, ranging 0-360, creates the Global Severity score. Higher scores indicate greater psychopathology.

Change in the World Health Organization Quality of Life questionnaire score, a 26-item assessment of overall quality of life. The questionnaire encompasses 4 domains: physical health, psychological health, social relationships, and environment. There are two additional questions, which assess the participant's perceptions of their own quality of life and physical health. Higher scores indicate better quality of life. Scores are summed within each domain. Total score is obtained by transforming for a total range of 0-100 within each domain.
