How does the brain decode the meaning of sound signals, such as music and courtship songs? We believe the fruit fly is an ideal model for answering this question. Fruit flies offer a comprehensive range of tools and assays which allow us to dissect the mechanisms underlying sound perception and evaluation in the brain. We recently have also started to investigate mosquitoes, as they use sound as part of their mating behavior. Interfering with these behaviors can prevent mosquitoes from mating, which opens new options for mosquito control.

Recent Activities

We develop fruit fly model to explore how learned auditory cues alter mating behavior and sexual preference.
We suggest that feed-forward inhibitory pathways in the fly brain adjust the behavioral response to courtship songs in female flies.
