Olfactory System in Drosophila

Abstract
Smell is an ancient sensory system presented virtually in organisms from bacteria tohumans. In Drosophila odors elicit a variety of behavioral responses in relatively simple butsensitive olfactory system. An increasing number of mutants have been found to be defective inolfactory function. Genetic and molecular analysis of the olfactory system of the fruit fly haveidentified many molecular components, and have revealed some principles of its function andorganization
