| Outline of Final Research Achievements |
Although many animals, including humans, use sound as a means of communication, the overall picture of the neural mechanisms responsible for the information processing has not been clarified. In this study, we used the Drosophila auditory system as an experimental model to understand the neural circuit mechanism for auditory information processing, such as recognizing species-specific communication sounds. We found that the pulse interval-selective response of AMMC-B1 neurons, which are secondary auditory neurons that play a central role in courtship song information processing, is formed by a feed-forward inhibitory pathway that is mainly driven by GABA-mediated inhibitory input.
