Top: averaged DGE in four-time blocks from one representative volunteer in different regions of interest (ROIs) before (block 1), during (block 2), and after (blocks 3 and 4) glucose infusion. Bottom: DGE changes over time in different ROIs from the same volunteer. The colored frame in the bottom time course indicates the time of glucose infusion.
