The researchers then recorded from motor nerves leaving the spinal cord. When blue light was shined directly on the spinal cord, walking-like activity began and was maintained for the duration of the light pulse. This proved that activation of Vglut2-expressing excitatory neurons in the spinal cord is sufficient for walking. Walking-like activity could also be initiated by exposing the lower brainstem to blue light, demonstrating that excitatory cells in the brainstem provide a sufficient 'go' signal to the spinal neurons involved in walking.
