FIG. 3.
BOLD activation during the WMT in control and type 1 diabetic (T1DM) subjects during euglycemia and hypoglycemia. Statistical parametric maps of regions of greatest activation during WMTs vs. control tasks for each subject group and glycemic condition. Functional activations (red-to-yellow color scale) are overlaid on the MNI-152 standard brain anatomy (gray scale). The threshold for activation was P < 0.05 after correction for multiple comparisons using the cluster-based threshold method (see research design and methods). During hypoglycemia, type 1 diabetic subjects exhibit greater activation than control subjects during the WMT. (A high-quality digital representation of this figure is available in the online issue.)
