Real-time biomimetic Central Pattern Generators into FPGA for hybrid experiments [PDF]
Frontiers in Neuroscience, 2013 This article investigates the neural network system in the leech heartbeat and develops a real-time biomimetic digital hardware using few-resource implementation for hybrid experiments. The leech heartbeat neural network is one of the most simple central

An optimality principle for locomotor central pattern generators [PDF]
Scientific Reports, 2021 Two types of neural circuits contribute to legged locomotion: central pattern generators (CPGs) that produce rhythmic motor commands (even in the absence of feedback, termed “fictive locomotion”), and reflex circuits driven by sensory feedback.

Why Firing Rate Distributions Are Important for Understanding Spinal Central Pattern Generators [PDF]
Frontiers in Human Neuroscience, 2021 Networks in the spinal cord, which are responsible for the generation of rhythmic movements, commonly known as central pattern generators (CPGs), have remained elusive for decades.

Key bifurcations of bursting polyrhythms in 3-cell central pattern generators. [PDF]
PLoS ONE, 2014 We identify and describe the key qualitative rhythmic states in various 3-cell network motifs of a multifunctional central pattern generator (CPG). Such CPGs are neural microcircuits of cells whose synergetic interactions produce multiple states with ...

Enhancing Legged Robot Locomotion Through Smooth Transitions Using Spiking Central Pattern Generators [PDF]
BiomimeticsIn this work, we propose the integration of a mechanism to enable smooth transitions between different locomotion patterns in a hexapod robot. Specifically, we utilize a spiking neural network (SNN) functioning as a Central Pattern Generator (CPG) to ...

Evolution of central pattern generators for the control of a five-link bipedal walking mechanism [PDF]
Paladyn, 2012 Central pattern generators (CPGs), with a basis is neurophysiological studies, are a type of neural network for the generation of rhythmic motion. While CPGs are being increasingly used in robot control, most applications are hand-tuned for a specific ...

A modeling approach on why simple central pattern generators are built of irregular neurons. [PDF]
PLoS ONE, 2015 The crustacean pyloric Central Pattern Generator (CPG) is a nervous circuit that endogenously provides periodic motor patterns. Even after about 40 years of intensive studies, the rhythm genesis is still not rigorously understood in this CPG, mainly ...

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
