Measured Sensitivity

Various presentation procedures and stimulus volumes were compared in their effect on salt taste sensitivity. For sodium chloride (NaCl) stimuli pipetted onto the tongue, subjects had comparable measured sensitivity to 10 ml and 1 ml volumes but a reduced sensitivity to 0.1 ml volumes. The greatest sensitivity was achieved with 10 ml sipped volumes. Modification of the Henkin dropwise triangluar taste test, by increasing the stimulus volumes, increased subjects' sensitivity. Only the 1 ml pipette presentation increased the sensitivity of the Henkin procedure, albeit slightly, to the detection of changes in taste sensitivity, the purpose for which the procedure was actually designed. Such modification did not perturb salivary NaCl levels more than the regular Henkin procedure, so it would not be expected to introduce sensitivity drift.

Sodium chloride (NaCl) stimulus residuals were seen to be greater after a large-volume NaCl rinse than after a small-volume rinse. Predicted changes in sensitivity dependent on adapting concentrations determined by residual levels were confirmed by signal detection R-index measures of sensitivity. R-index values were seen to be independent of the volume of the test water and NaCl stimuli used in their determination.

Male Patients

Taste sensitivity for sodium chloride in solution and sensitivity and preference for sodium chloride in bread were measured in 14 male patients undergoing hemodialysis. There was an increase in sensitivity to salt taste following dialysis only when assessed using the bread samples. Patients on a lower sodium diet were more sensitive to salt taste in bread. Although the taste changes were not related to the decreases in serum sodium or to copper, greater increases in sensitivity were related to greater increases in serum zinc during dialysis.

Taste Thresholds

The present study was designed to elucidate the differences in taste sensitivity in various strains of mice, and to study the relationship between taste sensitivity and color of the fur. Taste thresholds for four kinds of taste substance, i.e., sodium chloride, saccharine, acetic acid, and phenylthiocarbamide (PTC), were measured with three black and three white strains of mice. Taste sensitivity in mice with hypofunction of the suprarenal body, thyroid gland, and liver was also studied to clarify the bearing of the functions of those organs on the sense of taste. The taste sensitivity of mice differed according to strain. A white strain (aa) showed the lowest taste thresholds for all substances tested, whereas a black strain (0–61) showed the highest. Other strains showed intermediate thresholds, the white strains showing lower ones except in the case of saccharine. Hypofunction of the suprarenal body, thyroid gland, and liver caused a rise in the taste thresholds: a) after cauterization of the suprarenal body, the threshold for acetic acid was raised, whereas those for other taste substances were unchanged; b) reduction of thyroid and hepatic functions resulted in a rise of the taste thresholds for saccharine, acetic acid, and PTC.

Taste Detection

The R-index approach to the signal-detection P(A) index of sensitivity was used to measure taste sensitivity to NaCl solutions. The R-index is the predicted probability of the correct choice of a signal, for a given signal – noise pair. For flow-wise and sipwise presentation, R-indices did not fluctuate significantly, provided subjects could not see the stimuli yet to be presented, indicating a lack of systematic sensitivity drift. The simultaneous measurement of more than one signal strength with reference to a common noise stimulus was seen to be a viable and sensitive procedure. Comparison of flow-wise and sipwise presentation of stimuli using R-indices, indicated that the former elicited greater subject sensitivity to NaCl taste.
