... control because it contains central pattern generators (CPGs) – systems of coupled neuronal oscillators that provide coordinated rhythmic control of muscle activation that can be viewed as feedforward controllers – and multiple reflex loops that provide feedback mechanisms. These circuits are activated...

..., 1961 ), breathing( Lieske et al., 2000 ) and the grinding of food ( Marder,2000 ; Marder and Bucher,2001 ; Marder and Calabrese,1996 ) are usually produced by central pattern generators (CPGs). These CPGs are often multifunctional and comprise a large number of different motor outputs...

... and the associated abdominal ganglia containing the central pattern generator that drives oviposition digging. In this preparation it is possible to record simultaneously motoneurone activity, muscle electromyograms, intracellular muscle fibre activity and behaviourally relevant tension production. The muscle...
