Dynamic sensory cues shape song structure in Drosophila

摘要: The generation of acoustic communication signals is widespread across the animal kingdom, and males many species, including Drosophilidae, produce patterned courtship songs to increase their chance success with a female. For some animals, song structure can vary considerably from one rendition next; neural noise within pattern generating circuits widely assumed be primary source such variability, statistical models that incorporate are successful at reproducing full variation present in natural songs. In direct contrast, here we demonstrate much variability Drosophila explained by taking into account dynamic sensory experience male. particular, using quantitative behavioural assay combined computational modelling, find use fast modulations visual self-motion songs, relationship show evolutionarily conserved. Using circuit manipulations, also identify pathways involved patterning choices females sensitive features. Our data not only production fixed action pattern, but establish as valuable new model for studies rapid decision-making under both social naturalistic conditions.
