Influence of walking on swimmeret beating in the lobster Homarus gammarus
Abstract Influence of walking on swimmeret beating in intact lobsters, Homarus gammarus , has been analyzed using a treadmill experimental device. Belt movement activates both leg stepping and swimmeret beating. The simultaneity of the onset of the two motor systems in this situation is demonstrated...
