From Spinal Central Pattern Generators to Cortical Network: Integrated BCI for Walking Rehabilitation [PDF]

Neural Plasticity, 2012
Success in locomotor rehabilitation programs can be improved with the use of brain-computer interfaces (BCIs). Although a wealth of research has demonstrated that locomotion is largely controlled by spinal mechanisms, the brain is of utmost importance in

Multivariable Harmonic Balance for Central Pattern Generators. [PDF]

Automatica (Oxf), 2008
The central pattern generator (CPG) is a nonlinear oscillator formed by a group of neurons, providing a fundamental control mechanism underlying rhythmic movements in animal locomotion. We consider a class of CPGs modeled by a set of interconnected identical neurons.

Three-dimensional walking of a simulated muscle-driven quadruped robot with neuromorphic two-level central pattern generators

International Journal of Advanced Robotic Systems, 2019
We aim to design a neuromorphic controller for the locomotion of a quadruped robot with muscle-driven leg mechanisms. To this end, we use a simulated cat model; each leg of the model is equipped with three joints driven by six muscle models incorporating

NEURONpyxl: fast, flexible, Python-integrated simulation of biophysical neural networks with complex plastic synapses [PDF]

Frontiers in Computational Neuroscience
IntroductionNEURON has been widely used as an empirically-based simulation tool, especially for multi-compartment conductance-based neuronal modeling. The network mediating feeding in Aplysia californica has been extensively studied as a model central ...

The Complement of Projection Neurons Activated Determines the Type of Feeding Motor Program in Aplysia

Frontiers in Neural Circuits, 2021
Multiple projection neurons are often activated to initiate behavior. A question that then arises is, what is the unique functional role of each neuron activated? We address this issue in the feeding system of Aplysia.

Association Between Temporal Asymmetry and Muscle Synergy During Walking With Rhythmic Auditory Cueing in Survivors of Stroke Living With Impairments

Archives of Rehabilitation Research and Clinical Translation, 2022
Objective: To examine the relationship between temporal asymmetry and complexity of muscle synergy during walking using rhythmic auditory cueing (RAC) and the factors related to changes in muscle synergy during walking with RAC in survivors of stroke ...

Elimination of Left-Right Reciprocal Coupling in the Adult Lamprey Spinal Cord Abolishes the Generation of Locomotor Activity

Frontiers in Neural Circuits, 2017
The contribution of left-right reciprocal coupling between spinal locomotor networks to the generation of locomotor activity was tested in adult lampreys.

Sensor-Based Programming of Central Pattern Generators in Humanoid Robots

International Journal of Advanced Robotic Systems, 2013
In the present article, a method for generating curvilinear bipedal walking patterns is proposed which is able to generate rhythmic and periodic trajectories for a Nao soccer player robot. To do so, a programmable central pattern generator was used which

Rhythmic movements in sleep disorders and in epileptic seizures during sleep

Sleep Science and Practice, 2020
Rhythmic movements during sleep may occur in the context of physiological sleep-related motor activity or be part of sleep-related movement disorders such as bruxism, periodic limb movement disorder, restless legs syndrome, and sleep-related rhythmic ...
