Experience-induced changes in sugar taste discrimination.

abstract：:Phantosmia, the perception of an odor when there are no odorants in the environment, can be a very debilitating symptom. In the 1960s, Zilstorff reported olfactory distortions could be treated by the topical application of a cocaine solution to the olfactory epithelium. In evaluating this treatment, we observed no lon...
