title: Magnitude estimation of adaptation to salt using a flow chamber for stimulus delivery.
abstract: Adaptation course to NaCl was estimated using a flow chamber for stimulus delivery and changes in the perceived taste magnitude as the criterion. The adapting stimulus of different durations was applied to one side of the tongue. Magnitude estimates were made by comparing the intensity of taste at the end of each adaptation time with the perceived intensity of the same stimulus applied briefly to the unadapted side of the tongue. The course of adaptation followed a negatively accelerated decreasing function. The relationship between taste magnitude and the duration of the adapting stimulus can be approximated by a logarithmic equation and, somewhat less accurately, also by an exponential equation, which can be related to the Beidler theory of taste stimulation. Some advantages of the closed flow technique and comparison of taste magnitudes on the adapted and unadapted sides of the tongue are discussed.
