Rostral scratch motor neuron activity patterns in response to stimulation of a site in the right rostral scratch receptive field in a D3-end preparation. ENG recordings from the right knee-flexor nerve, the right biarticular knee-extensor nerve, the right monoarticular knee-extensor nerve, and the right hip-flexor nerve. (A) Normal rostral scratch. Knee-flexor activity marked with unfilled rectangles; biarticular knee-extensor quiescence marked with gray-filled rectangles. (B) Rostral scratch with hip-extensor deletions. Hip-extensor deletions marked with unfilled triangles; knee-flexor deletion marked with unfilled circle; rhythmic knee-flexor bursts during knee-extensor quiescence marked with unfilled diamonds.
