  author={Martin Golubitsky and Ian Stewart and Pietro-Luciano Buono and James J. Collins},
Animal locomotion is controlled, in part, by a central pattern generator (CPG), which is an intraspinal network of neurons capable of generating a rhythmic output1,2,3,4. The spatio-temporal symmetries of the quadrupedal gaits walk, trot and pace5,6,7,8 lead to plausible assumptions about the symmetries of locomotor CPGs9,10,11. These assumptions imply that the CPG of a quadruped should consist of eight nominally identical subcircuits, arranged in an essentially unique matter. Here we apply…

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.

Gait transition in a central pattern generator for bipeds ⋆

In this paper we study gait transition in a central pattern generator (CPG) model for bipedal locomotion. This model is proposed by Golubitsky, Stewart, Buono and Collins (14; 15) and is studied

Fractional central pattern generators for bipedal locomotion

Locomotion has been a major research issue in the last few years. Many models for the locomotion rhythms of quadrupeds, hexapods, bipeds and other animals have been proposed. This study has also been

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.

Complex Order Biped Rhythms

This paper considers a new complex order central pattern generator (CPG) model for locomotion in bipeds that is a generalization of the concept of an integer derivative and Parameter regions where periodic solutions, identified with legs' rhythms in biped, occur, are analyzed.

Gait Generation for a Bipedal System By Morris-Lecar Central Pattern Generator

This work exploits a bio-inspired method to generate different gaits in a bipedal locomotion system using the 4-cell CPG model developed by Pinto and uses the Morris-Lecar equations as internal nonlinear dynamics of the cells.

Gait generation and transition for a five-link biped robot by Central Pattern Generator

The results obtained in this work show the feasibility of using CPG-based methods to generate five-link biped locomotion and transitions between different gaits, and the periodic signals resulting of this model can be used as joint angles of hip and knee joints of a five- link biped robot.

Multistable phase regulation for robust steady and transitional legged gaits

We develop robust methods that allow the specification, control, and transition of a multi-legged robot’s stepping pattern, its ‘gait’, during active locomotion over natural terrain. Resulting gaits



Coupled nonlinear oscillators and the symmetries of animal gaits

The 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 locomotion.

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.

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.

Neurophysiology of locomotor automatism.

Although general features of the system controlling locomotion are more or less clear, many questions are not yet answered; it is unknown what relative contributions to motoneuronal activity are made by proprioceptive reflexes versus influences from the automatism of stepping.

Leg design in hexapedal runners.

To explain how diverse leg designs can result in common whole-body dynamics, a miniature force platform was used to measure the ground reaction forces produced by individual legs of the cockroach Blaberus discoidalis and showed that deviations from the minimum moments may be explained by considering the minimization of the summed muscle forces in more than one leg.

Are central pattern generators understandable?

A basic strategy that would provide sufficient information for neural modeling would include: identifying and characterizing each element in the CPG network; specifying the synaptic connectivity between the elements; and analyzing nonlinear synaptic properties and interactions by means of the connectivity matrix.

The quadrupedal gaits of vertebrates

Eccentric photographer Eadweard Muybridge was prompted to invent the first moving pictures to settle the question about trotting horses: if racing trotters ever have all feet off of the ground.

Comparative electromyography of the lower extremity in jogging, running, and sprinting

There was little or no activity in the gastrocnemius or in the intrinsic muscles of the foot about the time of toe-off, leading the authors to conclude that push-off per se does not appear to occur.
