Elements of Olfactory Receptor Coding in the Yellowfever Mosquito12

Abstract
Electrophysiological investigation of the primary olfactory afferent neurons on the antennae of female Aedes aegypti (L.) mosquitos disclosed 3 distinct physiological subdivisions of the neurons associated with the morphologically defined A2-type setae. These subdivisions are based on the spontaneous activities and specific responsiveness of the A2-type setae to selected chemical stimuli. The responses of the other setae were examined also, and elements of a peripheral input code are discussed.
