Fig 1. Voxel-based activation differences between groups in the posterior cingulate cortex/precuneus.

(A) Statistical activation map from voxel-based analyses, showing the location of activation differences between groups during the no-go > go contrast in the posterior node of the default mode network. (B) Percent signal change from this cluster indicated greater deactivation in the control (ctl) relative to the type 1 diabetes (T1D) group. Planned pairwise comparisons showed that this finding was driven by deactivation differences occurring during no-go trials. Error bars represent standard deviation. *p < 0.01, **p < 0.001.
