In joint with with Ian Stewart we have discussed how phase-synchronous signals can propagate along chains of neurons using a feedforward lift of the CPG and, given sufficient conditions for stability to synchrony-breaking perturbations. Here we apply these ideas to biped locomotion. The CPG &nbsp;concerned was introduced by Carla Pinto and Martin Golubitsky. Feedforward architecture propagates the &nbsp;phase pattern of a CPG along a chain of identical modules. For certain rate models, we give analytic conditions that are sufficient for transverse Liapunov and Floquet stability.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bio:<\/strong> Reader at the Mathematics Institute, University of Warwick.
