[Synchronization of electromyographic and cinematographic recordings. Applications to vertebrate biomechanics].
Synchronizing each frame of the cinema of a moving animal with the corresponding EMG of some muscles permits a precise interpretation of the variations of the electric potentials in that muscle with each phase of the movement. e.g. in the rabbit, three bundles of the masseter muscle function independently during the mastication; in the pigeon, electric potentials appear in both ilio-tibialis and biceps femoris muscles some frames before the actual raising of the leg, when the animal on its perch becomes out of balance.
