It is known since the pioneering work of Adrian in the 1931s that the completely isolated nervous system can generate impulse patterns that are correctly structured for commanding meaningful movements. This chapter addresses the question of how neurons form circuits that play specific functional roles in generating animal movements, particularly rhythmic movements. Several mechanisms by which simple circuits can generate rhythmic activity patterns are described. These include reciprocal inhibition in circuits comprising only two neurons, recurrent cyclic inhibition in three-neuron loops, and the basic circuit that generates swimming movements in the sea slug Tritonia.
Keywords: circuit, oscillation, rhythm, Tritonia, leech, reciprocal inhibition, recurrent cyclic inhibition, synaptic fatigue
