Abstract

In birds and higher mammals, auditory experience during development is critical to discriminate sound patterns in adulthood. However, the neural and molecular nature of this acquired ability remains elusive. In fruit flies, acoustic perception has been thought to be innate. Here we report, surprisingly, that auditory experience of a species-specific courtship song in developing Drosophila shapes adult song perception and resultant sexual behavior. Preferences in the song-response behaviors of both males and females were tuned by social acoustic exposure during development. We examined the molecular and cellular determinants of this social acoustic learning and found that GABA signaling acting on the GABAA receptor Rdl in the pC1 neurons, the integration node for courtship stimuli, regulated auditory tuning and sexual behavior. These findings demonstrate that maturation of auditory perception in flies is unexpectedly plastic and is acquired socially, providing a model to investigate how song learning regulates mating preference in insects.

Of numerous animals and you may birds keeps a life threatening several months for the youngsters whenever reading this new singing cues of their parents assists them to learn the specific popular features of their interaction sounds. Boffins had been taking a look at the minds out-of people, wild birds and other animals to find out what is happening within the its heads in the event the animals hear these types of musical. Yet not, the minds of those types are way too complex to totally see how very early singing affects contour your brain companies you to definitely control behavior. Sigue leyendo
