Quadrupedal locomotion arises from a complex interplay between spinal neuronal circuits, descending brain signals, musculoskeletal interactions, and sensory feedback, enabling adaptive speed and terrain dependent gait transitions. However, the underlying neural mechanisms involved in limb coordination are poorly understood. Here, we present a 3D closed-loop neuromechanical model of a mouse and use it to explore interactions between the spinal circuitry and afferent feedback and their role in interlimb coordination during quadrupedal locomotion. The spinal circuit model includes four rhythm gen
