[1B2] Taste and Smell

[1B2-03] Influence of the respiratory route on discriminating the odors

○Naohisa Nagaya¹, Akari Iwasaki¹, Hiroya Yamada¹ (1. Kyoto Sangyo University)

In order to clarify the functional role of two nasal cavities separately in human olfaction, we developed a device capable of presenting different odors to both nasal cavities and conducted experiments to see how odor is perceived. In the experiments, we conducted experiments under two conditions: expiration pass through the nose and pass through the mouth. As a result, the ratio of answering that it perceives odor to the nasal cavity opposite to the one on which odor was presented was significantly higher when a breath passed through the nose.
