Olfaction
Definition:
(n.) The sense by which the impressions made on the olfactory organs by the odorous particles in the atmosphere are perceived.
Example Sentences:
(1) There appears to be a perceptual limitation in olfaction relative to vision that influences stimulus encoding and stimulus retrieval processes but that does not affect retrieval of associated responses.
(2) Using this olfactory scale in the blotting paper test a rough quantitative screening of the degree of olfaction impairment should be possible, without recourse to expensive olfactometry.
