Fig. 11. Ensemble averages of electromyographic (EMG) activity of the longissimus
dorsi, revealing a consistent locomotor function but no ventilatory function.
Samples are from three dogs (A-C), and the average across three dogs (D), with
ventilatory (bold lines) and acceleration (thin lines) traces to reveal
relationships to breath and stride (E). IF indicates ipsilateral forelimb
support and CF contralateral forelimb support in the footfall bars at the
bottom. All traces are on the same time scale. Exp., expiration; Insp.,
inspiration.
