[Neurophysiologic patterns of movement control in free-moving Astacus astacus crayfish].
Studies have been made on the neuronal organization of muscular control in the dactylopodite during grasping the food by the claw, holding it by the dactyls, tranasportation to the mouth opening area and to the perioral organs. It was shown that in coordination relationships of efferent structures which control muscular efforts of the dactylopodite during realization of foodgrasping movements, the important role is played by afferent influences from hairy mechanoreceptors located on the inner surface of the claw dactyls, as well as by the influences from the receptors of the propo-dactylopodite specialized mechanoreceptor organ. Operation of these sources of afferent influences seems to be the main principle of organization of minimal biological information-control system.
