We focus on acoustically communicating insects to explore how the nervous system controls the generation of sound signals, and how nerve cells in the brain process these signals to allow species-specific recognition. In this way we use these insects as model systems to reveal fundamental principles of neuronal processing at the level of networks, nerve cells and molecules.
Current research topics include:
- Lifetime development of phonotactic behaviour
- The neuromuscular basis of acoustic steering in walking crickets
- Studying the neurons for pattern recognition in the brain
- The control of singing by command neurons
- The neuronal basis of species-specific singing behaviour
- Calcium imaging of auditory processing
