to determine whether insulin per se alters brain glucose metabolism , we measured glucose utilization rates , using the deoxyglucose method , in the medial basal hypothalamus , locus coeruleus , and motor cortex of conscious , unrestrained rats undergoing 2-h euglycemic clamps ( blood glucose , 4.1 +/- 0.1 mmol/liter ) at increasing insulin infusion rates .
