Neural circuit mechanisms of feeding regulation in Drosophila
The neural basis of nutrient-specific feeding behavior
Our lab is interested in the neural mechanism that controls nutrient-specific feeding behavior. By employing molecular biology, neurogenetics, behavior, and functional imaging techniques, we use Drosophila as a model organism to explore the following questions:
- What is the neuronal substrate that orchestrates protein-feeding behavior?
- How are different nutrient-specific signals integrated in central circuits to regulate feeding?
- How do internal states regulate feeding through neuromodulation of different feeding circuits?
