The Zebrafish Neural Circuits and Behavior Laboratory researches the neural circuits underlying locomotor behavior in the larval zebrafish. These tiny fish with transparent bodies are ideal for studying in real time how the brain and spinal cord work together to produce everyday movements the fish needs to swim around its environment. The techniques we employ are multidisciplinary, including high-speed behavioral recordings and analysis, dynamic imaging of calcium activity within populations of neurons and electrophysiology. Using these techniques, we try to understand what specific circuits are essential for performing different motor actions and how those circuits are wired together.
