  • Brain levels of glycogen were not affected by starvation. Male Sprague Dawley rats were starved for 12 hr starting at 6:00 P.M. (lights out) and killed at 6:00 A.M. by 10 kW of focused microwave irradiation. Glycogen levels were measured in isolated brain regions and data are mean ± SEM values from four animals in each group.
