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. Olfaction. Coding.
