Abstract
We measured the temperature of arterial blood within the circle of Wil lis (T(willis)) in seven normothermic patients undergoing carotid arte riography. We found this temperature to be lower by 0.13 to 0.30-degre es-C than tympanic temperature and by 0.30 to 0.55-degrees-C lower tha n rectal temperature. By imposing this data on calculated cerebral hea t balance it can be suggested that the average cerebral temperature of a resting subject is somewhat higher than tympanic temperature. These findings would also support indirectly the thesis that temperature gr adients may exist within the brain.
