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.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324416880">Определяющая роль сенсорного входа в инициации и модуляции локомоции показана неоднократно. Одним из способов изучения этого входа является парадигма “расщепленного” тредбана. В настоящем исследовании проведен сравнительный анализ ходьбы децеребрированной кошки по расщепленному тредбану, ленты которого двигались не только с разными скоростями (различались в 3 раза), но и в разных направлениях (вперед и назад). Показана реципрокная работа двух конечностей, а также мышц-сгибателей и разгибателей каждой конечности при таком локомоторном режиме. Выявлены две основные стратегии ходьбы: в ответ на один шаг конечности, идущей по медленной ленте тредбана, конечность, идущая по быстрой ленте, делала или один (стратегия 1 : 1), или два шага (стратегия 1 : 2); стратегии могли чередоваться. Результаты исследования позволяют предположить сохранение интеграции локомоторных сетей двух конечностей при значительном рассогласовании их сенсорных входов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bidirectional walking</kwd><kwd>central pattern generator</kwd><kwd>split treadmill</kwd><kwd>spinal cord</kwd><kwd>decerebration</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>двунаправленная ходьба</kwd><kwd>центральный генератор паттерна</kwd><kwd>расщепленный тредбан</kwd><kwd>спинной мозг</kwd><kwd>децеребрация</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Вещицкий А.А., Ляховецкий В.А., Горский О.В., Мусиенко П.Е., Меркульева Н.С.
