Tsunoda Lab

The Tsunoda lab works on the regulation and plasticity of ion channels and receptors in response to changes in neural activity. Recent projects in the lab have examined homeostatic synaptic plasticity mediated by nicotinic acetylcholine receptors and the voltage-gated Kv4 potassium channel in the model system of Drosophila melanogaster. The lab utilizes a variety of approaches, including electrophysiology, genetics, molecular and cell biology, and behavior.
