Abstract— A method has been developed for the simultaneous measurement of the rates of glucose consumption in the various structural and functional components of the brain in vivo. The method can be applied to most laboratory animals in the conscious state. It is based on the use of 2‐deoxy‐D‐[ 14 C]glucose ([ 14 C]DG) as a tracer for the exchange of glucose between plasma and brain and its phosphorylation by hexokinase in the tissues. [ 14 C]DG is used because the label in its product, [ 14 C]deoxyglucose‐6‐phosphate, is essentially trapped in the tissue over the time course of the measurement. A model has been designed based on the assumptions of a steady state for glucose consumption, a first order equilibration of the free [ 14 C]DG pool in the tissue with the plasma level, and relative rates of phosphorylation of [ 14 C]DG and glucose determined by their relative concentrations in the precursor pools and their respective kinetic constants for the hexokinase reaction. An operational equation based on this model has been derived in terms of determinable variables. A pulse of [ 14 C]DG is administered intravenously and the arterial plasma [ 14 C]DG and glucose concentrations monitored for a preset time between 30 and 45min. At the prescribed time, the head is removed and frozen in liquid N 2 ‐chilled Freon XII, and the brain sectioned for autoradiography. Local tissue concentrations of [ 14 C]DG are determined by quantitative autoradiography. Local cerebral glucose consumpt...
