Modeling temporal coordination in speech production using an artificial central pattern generator neural network
… and more recently, some suprasegmental timing patterns. This dissertation explores how different levels of phonological organization (the gesture, syllable, stress group, and phrase) are coordinated in speech production by measuring the effects of that coordination on acoustic and behavioral …

Centrinių sekų generatorių algoritmų grįstų roboto judesių gerinimas /
… of robotics and Nature working together is central pattern generators – neural circuits found inside animals that are responsible for generating rhythmic, repetitive signals without the interference from a higher level control system. The central pattern generator algorithm was adapted for …

MASSIVELY DISTRIBUTED NEUROMORPHIC CONTROL FOR LEGGED ROBOTS MODELED AFTER INSECT STEPPING
… on insect neurobiology. Each joint uses a unique central pattern generator (CPG) to produce oscillation. The CPGs in each leg cannot directly communicate, but are coordinated by sensory influences, producing stepping motion. One CPG from each leg receives input from the same CPG in other legs, …

Humanoid Robot Soccer Locomotion and Kick Dynamics: Open Loop Walking, Kicking and Morphing into Special Motions on the Nao Robot
… The solution we develop involves the design of a central pattern generator to allow for controlled steps with realtime accuracy, and a phase locked loop method to synchronise with the Aldebaran walk so that precise step length control can be activated when required. An open loop trajectory mapping …

Cellular signalling pathways involved in thermoprotection of neural ciruit function in the locust.
… temperature fluctuates. Most animals have central nervous system (CNS) responses to heat shock (HS) preconditioning which extend the thermal operating range of neural circuits during exposure to extreme heat. It is unclear how HS preconditioning confers CNS thermotolerance. I used the …

Real time evolutionary algorithms in robotic neural control systems.
… accordingly. The project initially developed a Central Pattern Generator (CPG) for a Bipedal Robot and used this to explore the basic characteristics of RTEA. The system was then developed to operate on a Quadruped Robot and a test regime set up which provided thousands of real-environment like …

Feasibility of novel gait training with robotic assistance : dynamic entrainment to mechanical perturbation to the ankle
… self-sustaining neural oscillator (a rhythmic pattern generator) encapsulated the essence of these observations. This suggests that several prominent limit-cycle features of human walking may stem from peripheral mechanics mediated by simple afferent feedback without significant involvement of …

Neuroinspired control strategies with applications to flapping flight
… for analysis and design. First, we consider central pattern generators (CPGs) to control flapping-flight dynamics. The key idea here is dimensional reduction - we want to convert complicated interactions of many degrees of freedom into a handful of parameters which have intuitive connections …

Neuromorphic auditory computing: towards a digital, event-based implementation of the hearing sense for robotics
… audio processing architectures. An audio-guided central pattern generator was used to control a hexapod robot in real-time using spiking neural networks on SpiNNaker. Then, a sensory integration application was implemented combining sound source localization and obstacle avoidance for autonomous …

Addressing Indirect Functional Connectivity in Neuroscience via Graphical Information Theory: Causality and Coherence
… GDI inferred many connections of a model of a central pattern generator (CPG) circuit in Aplysia, while also reducing many indirect connections. GDI can be used on a variety of scales and data types to provide accurate direct causal connectivity graphs. Our second model-free framework, partial …

Respiratory function: A systems approach
… Neurons inside the MPRC are organized into a central pattern generator (CPG), the functionality of which is not clearly understood. Although intracellular recordings have established the stimulus-induced response of isolated respiratory neurons in specific locales of the brain stem, the …

Biologically-inspired control framework for insect animation.
… two key observations of real insects: fixed gait pattern and distributed neural system. At the top level, a Triangle Placement Engine (TPE) is modelled based on the double-tripod gait pattern of insects, and determines the location and orientation of insect foot contacts, given various user …

Stable locomotion control of bipedal walking robots : synchronization with neural oscillators and switching control
… inspired control with neural oscillators (central pattern generator, abbreviated as CPG) is used for global stable locomotion of bipeds based on a mutually inhibited neural oscillator model (Matsuoka, 1985). A systematic design approach is studied for the entrainment between the dynamics of …

A computational and experimental study of the Drosophila larval locomotor system and its developmental critical period
… thesis is to further our understanding of the central pattern generator underlying Drosophila larval locomotor network and how it is affected by transient manipulations present during its developmental critical period. First, I developed a computational model of the central pattern generator …

Mechanisms of ionic current changes underlying rhythmic activity recovery after decentralization
… generating rhythmic output in the absence of patterned sensory or central inputs are widely represented in the nervous system where they support a variety of functions, from learning and memory to rhythmic motor activity such as breathing. To perfectly function in a living organism, …

Biophysical Model of Retraction Motor Neurons and Their Modification by Operant Conditioning
… modified by OC. This behavior is mediated by a central pattern generator (CPG) network in the buccal ganglia that contains a relatively small number of neurons. This CPG generates rhythmic motor patterns (BMPs) that move food into the gut by closing a tongue-like structure (i.e., radula) during …
