In this study, we present a novel model for Huntington's disease (HD) gait disorder. We consider the mathematical relations between blocks. The number of inputs and outputs of each block are designated due to the physiological findings. The connection types between blocks are mod
AmphiBot II: An Amphibious Snake Robot that Crawls and Swims using a Central Pattern Generator
This article presents AmphiBot II, an amphibious snake robot designed for both serpentine locomotion (crawling) and swimming. It is controlled by an on-board central pattern generator (CPG) inspired by those found in vertebrates. The CPG is modelled as a chain of coupled nonlinea
Stimulus-Dependent Polyrhythms of Central Pattern Generator Hardware
We have built universal central pattern generator (CPG) hardware by interconnecting Hodgkin-Huxley neurons with reciprocally inhibitory synapses. We investigate the dynamics of neuron oscillations as a function of the time delay between current steps applied to individual neurons
Central pattern generators and the control of rhythmic movements
Central pattern generators are neuronal circuits that when activated can produce rhythmic motor patterns such as walking, breathing, flying, and swimming in the absence of sensory or descending inputs that carry specific timing information. General principles of the organization
Central Pattern Generator Control of a Tensegrity Based Swimmer
There has been an increased interest in the development of biologically inspired vehicles and robotics, as they have the potential of outperforming the current state of the art in metrics of efficiency, economy, maneuverability, and stealth. In marine applications, unmanned under
Whisker deafferentation and rodent whisking patterns: behavioral evidence for a central pattern generator.
Even in the absence of explicit stimulation, rats emit patterns of rhythmic whisking movements. Because of their stereotyped nature and their persistence after sensory denervation and cortical ablation, whisking movements have been assumed to reflect the output of a central patte
Asymmetry Factors Shaping Regular and Irregular Bursting Rhythms in Central Pattern Generators
Central Pattern Generator (CPG) circuits are neural networks that generate rhythmic motor patterns. These circuits are typically built of half-center oscillator subcircuits with reciprocally inhibitory connections. Another common property in many CPGs is the remarkable rich spiki
Stable Modifiable Walking Pattern Generator with a Vertical Foot Motion by Evolutionary Optimized Central Pattern Generator
This paper proposes a stable modifiable walking pattern generator with a vertical foot motion generated by a central pattern generator that is obtained from the evolutionary constrained optimization. A modifiable walking pattern generator is employed which generates sagittal and
Control of Cat Walking and Paw-Shake by a Multifunctional Central Pattern Generator
Central pattern generators (CPGs) are oscillatory neuronal networks controlling rhythmic motor behaviors such as swimming, walking, and breathing. Multifunctional CPGs are capable of producing multiple patterns of rhythmic activity with different periods. Here, we investigate whe
Walking Pattern Generator Using an Evolutionary Central Pattern Generator
For the generation of locomotion, such as walking, running or swimming, vertebrate and invertebrate animals use the Central Pattern Generator (CPG). In this paper, a walking pattern generator is proposed using an evolutionary optimized CPG. Sensory feedback pathways in CPG are pr
