Locomotion is crucial for an animal’s survival. Despite its importance, our understanding of how movement is generated is limited. Zebrafish (Danio rerio) is a commonly used animal to study the spinal control of movement. Many neuronal populations found in zebrafish are evolutionarily conserved across species, including mammals. Even as early as 4-5 days post fertilization, larval zebrafish display a wide range of swimming speeds measured in tail beat frequencies, making it a great model to study locomotor control. Experimental studies have identified several populations of spinal neurons comp
