Central pattern generators (CPGs) have traditionally been modeled as sets of cou-
pled bistable oscillators [2]. We present a framework for constructing models which
avoid the shortcomings of these traditional models, while remaining biologically
plausible. We demonstrate our approach by generating a novel model of lamprey
locomotion. However, we suggest that the methods presented here can be more gen-
erally applied to modeling any neural system which produces and controls dynamic
patterns of forces.
Key words: Central pattern generator; CPG; Neural computation; Lamprey
locomotion; Coupled oscillators
