Metabolic activation of the brachium conjunctivum during induced hypothermia

During hypothermia induced in ground squirrels by the halothane-heliox method, 2-deoxyglucose uptake of a white matter structure, the brachium conjunctivum, increased relative to the surrounding gray matter structures. The possibility of 2-deoxyglucose uptake by glial as well as neuronal elements in the brachium conjunctivum and the implications of this observation for the use of optical density ratios is discussed.
