An oscillatory intersegmental neuronal network drives the swimming rhythm of the leech. This network consists of interneurons joined via inhibitory connections to form a series of segmentally iterated, concatenated rings. Recurrent cyclic inhibition in these rings produces a multiphasic activity rhythm. By theoretical analysis of such concatenated interneuronal rings and construction of their electronic analogs it is shown that the interneural network identified in the central nervous system of the leech has properties appropriate for generating the observed motor output.
