Innate recognition of pheromone and food odors in moths: a common mechanism in the antennal lobe?

摘要: The survival of an animal often depends on innate response to a particular sensory stimulus. For adult male moth, two categories odors are innately attractive: pheromone released by conspecific females, and the floral scents certain, co-evolved, plants. These consist multiple volatiles in characteristic mixtures. Here, we review evidence that both processed as objects, suggest mechanism primary olfactory center, antennal lobe (AL), encodes configuration these mixtures may underlie recognition attractive odors. In system, or three elicit upwind flight. Peripheral changes associated with behavioral speciation, existence pattern for AL. Moths similarly attracted certain scents. Though activate broad array receptor neurons, only smaller subset, numerically comparable mixtures, is necessary sufficient behavior. Both scent produce attraction odor source synchronous action potentials populations output (projection) neurons (PNs) We propose model which population PNs mixture, thus comprises releasing odor-tracking example olfaction moths inform general question how objects trigger responses.
