The caloric stimulus: mechanisms of heat transfer.
This review is concerned with the physical processes involved in thermal stimulation of the vestibular end-organ. A brief outline of the anatomy of the end-organ is given with particular reference to the horizontal semicircular canal, followed by a description of end-organ hydrodynamics. The neurophysiological mechanisms of thermal stimulation are then considered. Finally, routes of heat transfer from outer to inner ear are discussed.
