N2 - The decisive role of sensory input in the initiation and modulation of locomotion has been shown repeatedly. One way to explore this input is the "split" treadmill paradigm. In the present study, a comparative analysis of the walking of a decerebrate cat on a split treadmill was carried out, the belts of which moved not only at different speeds (differed by 3 times), but also in different directions (forward and backward). The reciprocal work of two limbs, as well as the flexor and extensor muscles of each limb, is shown in such a locomotor mode. Two main walking strategies were identified: in response to one step of the limb walking along the slow treadmill belt, the limb walking along the fast belt made either one (1:1 mode) or two steps (1:2); strategies could interchange. The results of the study suggest the preservation of the integration of the locomotor networks of the two limbs with a significant mismatch of their sensory inputs.
