TY - GEN T1 - An odor is not worth a thousand words from multidimentional odors to unidimentional odor objects.[article]. A1 - Yeshurun, Yaara LA - English UL - https://tuklas.up.edu.ph/Record/UP-8027390931312409693 AB - Olfaction is often referred to as multidimentional sense. It is multidimentional in that ~1000 different receptor types, each tuned to particular odor aspects, together contribute to the olfactory percept. In humans, however, this percept is nearly unidimentional. Humans can detect and discriminate countless odorants, but can identify few by name. The one thing humans can do invariably say about an odor is whether it is pleasant or not. We argue that this hedonic determination is the key function of olfaction. Thus, the boundaries of an odor object are determined by its pleasantness, whic-unlike something material and more like an emtion-remains poorly delineated with words. KW - Olfaction. KW - Coding.
