Tympanic thermometry: an index of hemispheric activity.
This article describes the use of tympanic thermometry in investigations of hemispheric specialization. Subjects were asked to perform tasks known to be performed preferentially by the right or left hemisphere while fluctuations in tympanic temperature (reflecting changes in hemispheric metabolic activity) were recorded from thermal sensors placed in their outer ear canals. The analyses show that subjects who evince relatively higher elevations in metabolic activity (as measured through tympanic thermometry) in the hemisphere specialized for the task obtain better performance scores than those who show a reversed bias.
