Abstract
When two taste stimuli are presented, one to each side of the tongue, with a time delay of up to 1 msec., the taste sensation seems to move across the tongue. This phenomenon which is similar to directional hearing, can be used to show periodic fluctuations in sensation magnitude as well as other aspects of sensation. When the apparatus was refined to present taste stimuli, it was possible to observe rhythmic changes in the perception of taste. An analogy is demonstrated between hearing and taste sensation, even to some quantitative values.
