abstract = {Detailed neural network models of animal locomotion are
important means to understand the underlying mechanisms that
control the coordinated movement of individual limbs.
Daun-Gruhn and Tóth, Journal of Computational Neuroscience
31(2), 43–60 (2011) constructed an inter-segmental network
model of stick insect locomotion consisting of three
interconnected central pattern generators (CPGs) that are
associated with the protraction-retraction movements of the
front, middle and hind leg. This model could reproduce the
basic locomotion coordination patterns, such as tri- and
tetrapod, and the transitions between them. However, the
analysis of such a system is a formidable task because of
its large number of variables and parameters. In this study,
we employed phase reduction and averaging theory to this
large network model in order to reduce it to a system of
coupled phase oscillators. This enabled us to analyze the
complex behavior of the system in a reduced parameter space.
In this paper, we show that the reduced model reproduces the
results of the original model. By analyzing the interaction
of just two coupled phase oscillators, we found that the
neighboring CPGs could operate within distinct regimes,
depending on the phase shift between the sensory inputs from
the extremities and the phases of the individual CPGs. We
demonstrate that this dependence is essential to produce
different coordination patterns and the transition between
them. Additionally, applying averaging theory to the system
of all three phase oscillators, we calculate the stable
fixed points - they correspond to stable tripod or tetrapod
coordination patterns and identify two ways of transition
between them.},
