Outline of Final Research Achievements |
We developed a device for olfactory stimulation via ortho and retronasal routes synchronized with breath. We found that a retronasal odor after drinking enhanced taste, but an orthonasal odor before drinking did not. These results show that congruency with the natural temporal order of stimuli is a determining factor for odor-induced taste enhancement. Temporal resolution of simultaneity judgment with an unusual pair of gustation and olfactory stimuli did not differ from those of the normal pair of physical senses, whereas the temporal resolution of the usual pair of chemical senses was reduced compared to than that of unusual pair. In addition, we found that the P1 amplitude of the Event-related potential was large for simultaneous taste and olfactory stimulation. Our study in toddlers showed odor, which is familiar from infancy, more greatly enhances the intake of a sweet solution than does a novel odor. In addition, the congruency of taste and olfaction in mice changes with learning.
