SummaryAnimal locomotion typically employs several distinct periodic patterns of leg movements, known as gaits. It has long been observed that most gaits possess a degree of symmetry. Our aim is to draw attention to some remarkable parallels between the generalities of coupled nonlinear oscillators and the observed symmetries of gaits, and to describe how this observation might impose constraints on the general structure of the neural circuits, i.e. central pattern generators, that control…

Hexapodal gaits and coupled nonlinear oscillator models

The present analysis leads to a natural classification of hexapodal gaits by symmetry and to natural sequences of gait bifurcations, which relates observed gaits to the overall organizational structure of the underlying CPG.

Symmetry in locomotor central pattern generators and animal gaits

It is suggested that symmetry can be used to infer a plausible class of CPG network architectures from observed patterns of animal gaits, including a distinction between primary and secondary gait, the existence of a new primary gait called ‘jump’, and the occurrence of half-integer wave numbers in myriapod gaits.

Coupled chaotic oscillators and their relation to a central pattern generator for artificial quadrupeds

This work proposes to extend the CPG symmetries of the gaits of quadrupeds and bipeds using coupled chaotic oscillators synchronized using the Pyragas method and evaluates the time series behavior when the foot is in contact with the ground: this has potential robotic applications.

Models of central pattern generators for quadruped locomotion I. Primary gaits

The proposed network of symmetrically coupled cells modeling central pattern generators for quadruped locomotion is shown to be the simplest one, and a general theorem classifying spatio-temporal symmetries of periodic solutions to equivariant systems of differential equations is proved.

Hard-wired central pattern generators for quadrupedal locomotion

It is demonstrated that a hard-wired CPG model, made up of four coupled nonlinear oscillators, can produce multiple phase-locked oscillation patterns that correspond to three common quadrupedal gaits — the walk, trot, and bound.

Symmetry-Breaking in a Rate Model for a Biped Locomotion Central Pattern Generator

Methods from symmetric bifurcation theory are used to investigate local b ifurcation, both steady-state and Hopf, for their network architecture in a rate model and apply to rate equations on more general networks.

Models of central pattern generators for quadruped locomotion. I. Primary gaits.

It is shown that under mild assumptions on the cells and the coupling of the network, primary gaits can be produced from Hopf bifurcation by varying only coupling strengths of the Network of symmetrically coupled cells.

Gait Transitions in a Phase Oscillator Model of an Insect Central Pattern Generator

Here, the effect of stepping frequency on gait transition in an ion-channel bursting neuron model in which each cell represents a hemisegmental thoracic circuit of the central pattern generator is studied.

Phase locking in coupled oscillators as hybrid automata

This work has mapped out the synchronization behavior of CCM networks of various topologies parametrically, and developed a section-map analysis approach that exploits the polyhedral geometry of the hybrid state space.



Symmetry-breaking bifurcation: A possible mechanism for 2:1 frequency-locking in animal locomotion

In the present work, the quadrupedal locomotor central pattern generator is modelled as four distinct but symmetrically coupled nonlinear oscillators, showing that the typical patterns for two such networks of oscillators include 2:1 frequency-locked oscillations.

Modeling of a Neural Pattern Generator with Coupled nonlinear Oscillators

The generalized CPG model is shown to be versatile enough that it can also generate various n-legged gaits and spinal undulatory motions, as in the swimming motions of a fish.

The symmetries studied describe motion of the body and legs in terms of even and odd functions of time to describe symmetric running for systems with any number of legs and for a wide range of gaits.

Patterns at primary Hopf bifurcations at a plexus of identical oscillators

Mathematically, an oscillator is a system of ordinary differential equations with a periodic limit cycle, usually arising from a Hopf bifurcation for a stationary solution. A plexus is a collection

The theory of Hopf bifurcation with symmetry developed by Golubitsky and Stewart (1985) is applied to systems of ODEs having the symmetries of a regular polygon, that is, whose symmetry group is
