Research summary

Biophysics and neurophysiology of voltage gated ion channels; neuronal firing mechanisms; neurobiology of respiration

Research description

We investigate how voltage-gated ion channels determine the firing activity of individual neurons, and how neurons interact to generate distinct network behaviors. We address these questions in a brain slice preparation containing the pre-Bötzinger respiratory pacemaker, using patch-clamp electrophysiology, multiphoton imaging, real-time biological-computational models, maximum likelihood algorithms, and software development.
