A model of leg coordination in the stick insect, Carausim morosus

IV. Comparisons of different forms of coordinating mechanisms

Biological Cybernetics volume 66, pages 345–355 (1992)Cite this article

Abstract

The kinematic model presented in a separate report is used here to investigate several questions concerning the nature of the coordinating mechanisms. First, one or more mechanisms are inactivated in order to compare the relative efficiencies of the different coordinating mechanisms in maintaining proper coordination. Second, the most efficient mechanism, the position-dependent influence, is varied in order to illustrate the consequences for coordination. Third, the strength of the contralateral coupling is varied in order to make predictions about how contralateral legs establish alternation when started from symmetric positions. The consequences of adding reciprocal contralateral inhibition during swing is tested in the same context.
