Swimmeret in Crayfish Biological Sciences and Neurological University, Stanford 94305, and Department California, San Diego, La Jolla, California SEQUENCES Sciences Program, Neurosciences, 92037 ORDERLY muscular contractions MATERIALS AND METHODS occur during locomotion. To accomplish such behavior, the neuronal center controlling each limb must receive information about the contraction state in other limbs. Information this kind might involve timing cues from sensory input, from a set other local centers, or from a single âmasterâ center (1, 11). Hughes and Wiersma (5), Ikeda and Wiersma (6), and Wiersma and Ikeda (10) have shown that the in tersegmental control crayfish swimmeret beating is dependent neither on sensory input nor on a single master center; that nonsensory timing they proposed information transferred among segmental oscillators is sufficient to produce ly coordinated motoneuron activity. Central neurons which are active during the discharge specific swimmeret motoneurons were- isolated from the interganglionic connectives by Hughes and Wiersma (5) and Wiersma and Hughes (9), who suggested that these cells might be influential in coupling the movements the . The present study provides evidence in support the hypothesis that these neurons are, in fact, coordinating fibers. It is shown first that their discharge is not dependent on
