      abstract     = {Previous authors have proposed two basic hypotheses about
                      the factors that form the basis of locomotor rhythms in
                      walking insects: sensory feedback only or sensory feedback
                      together with rhythmic activity of small neural circuits
                      called central pattern generators (CPGs). Here we focus on
                      the latter. Following this concept, to generate functional
                      outputs, locomotor control must feature both rhythm
                      generation by CPGs at the level of individual joints and
                      coordination of their rhythmic activities, so that all
                      muscles are activated in an appropriate pattern. This work
                      provides an in-depth analysis of an aspect of this
                      coordination process based on an existing network model of
                      stick insect locomotion. Specifically, we consider how the
                      control system for a single joint in the stick insect leg
                      may produce rhythmic output when subjected to ascending
                      sensory signals from other joints in the leg. In this work,
                      the core rhythm generating CPG component of the joint under
                      study is represented by a classical half-center oscillator
                      constrained by a basic set of experimental observations.
                      While the dynamical features of this CPG, including phase
                      transitions by escape and release, are well understood, we
                      provide novel insights about how these transition mechanisms
                      yield entrainment to the incoming sensory signal, how
                      entrainment can be lost under variation of signal strength
                      and period or other perturbations, how entrainment can be
                      restored by modulation of tonic top-down drive levels, and
                      how these factors impact the duty cycle of the motor
                      output.},
