Stimulation of LMNs from cortical signals in guinea pigs during treadmill talking at 5.6 cm/s. A. Representative 17-s period of M1 and EMG recordings. B. Corresponding LHL and LFL movements. C. Time lag of intact LFL and stimulated LHL movements at different treadmill speeds. Data points were sampled from three animals (n = 10 per animal) and compared between different speeds within animals (**p < 0.01, t-test).
