We humans walk with our feet. This is true, but not entirely. Walking, as part of locomotion, is a coordinated whole-body movement that involves both the arms and legs. Researchers have identified different subpopulations of neurons in the spinal cord with long projections. These results show that these neurons coordinate movement of arms and legs and ensure a stable body posture during locomotion.
