Three new model systems for the study of rhythm generation in the isolated insect central nervous system are presented. Natural behavioral rhythms are produced in these cases spontaneously in the isolated CNS. They can be monitored as output of motoneurons at peripheral nerves. Recording from the neurons of the pattern generating networks during this output gives insight into neural control principles of locust respiration, of hemolymph pumping in accessory pumping organs of crickets, and of crawling movements in larvae of the weevil Rhynchophorus ferrugineus.
