masked with the NC group map and BD>NC comparisons with the BD group map). Figure 1 depicts the mean group DMN images from the higher-level analysis. An identical analysis was next carried out using the V1 template instead of DMN. This analysis examined spatial extent differences in the V1 component as a control network (template courtesy of Dr. Michael D. Greicius, Stanford University, Stanford, CA). These analyses were not corrected for multiple comparisons.
