| Outline of Final Research Achievements |
Many animals use the courtship sound in their mating behaviors. The courtship sound emitted by the sender gradually affects the receiver’s mating drive, which finally leads to its rejection of acceptance. We studied how the courtship sound is accumulated in the receiver’s brain and evokes an appropriate mating decision. Firstly, we mapped the auditory neural circuits in the fly brain by identifying interneurons that project to the primary auditory center. Secondly, we identified the feed-forward circuit that tunes the selectivity for a species-specific rhythm in the courtship sound. Finally, we found that an experience of hearing the conspecific song as a young adult sharpens the song preference and mate selection as a breeding adult. Together, we revealed a mechanism underlying the information processing and memory formation of the courtship sound in the fruit-fly brain.
