A METHOD OF CONTINUOUS REGISTRATION OF LOCAL CEREBRAL BLOOD FLOW IN ACUTE AND CHRONIC EXPERIMENTS,

Abstract

A more accurate measure of the blood flow to the brain can be obtained by increasing the power supply to the bridge of electrodes which have been permanently inserted in brains of laboratory animals. The thermistor will then heat up. With a change in the amount of current flowing across the bridge, a thermoresistance heating to one degree higher than the temperature of the inflowing blood is obtained. The higher the density and heating conductivity of the ambient medium, the greater must be the current strength flowing through the thermoelectrodes. The advantages of this method for registering blood flow are the simplicity of the attachment regulating the power supplies to the bridge, and the significant increase in sensitivity in registering blood flow by thermoresistance.
