Howeve, the thresholds for different odorants may range from 10-12 M to 102 M. 1.5. The exponent for odors is always less than unity. Responses to mixtures of chemical stimuli 1.6.1. The magnitude of taste sensation evoked by each of two chemicals in solution is decreased by mixing them. Suppression between taste qualities can be predicted by the power law.
Olfaction has both analytic and synthetic properties.
The relationship between area and stimulus intensity is described as this equation. In response to the steady stimulation, the sensory systems adjust themselves to be maximally sensitive to changes in stimuli near the prevailing intensity. Adaptation might decrease sensation magnitude. Adaptation might increase the ability to discriminate among stimuli that are similar to the adapting stimulus.
