title: [Peripheral and central factors which modify the taste threshold].
abstract: Several anatomical, physiological and behavioral factors have part in changing the values of the detection threshold, among which the reflexly secreted oral fluid. The HCl molar concentration appears to be a hyperbolic function of preference (= taste solution/water ratio); the empirical formula of the function makes the HCl molar concentration to be known, at which the same voll. of water and taste solution are drunk, i.e. the taste threshold.
