Research Interests

Development and plasticity of motor networks

Repetitive movements, like walking or breathing, are generated by networks of rhythmically active neurons. We are interested in how rhythmic networks develop and produce movements of different speeds and intensities. To do this, we study the spinal networks controlling innate motor behaviors in developing zebrafish. Zebrafish provide a unique opportunity to combine imaging, electrophysiological and molecular approaches to examine the neural control of behavior in the living organism. By revealing common principles of organization, we hope to provide insights into disorders that affect our capacity to move, like Parkinson’s disease, epilepsy or spinal injury.
