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, …

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 …

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 …

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 …

Ventilatorische Rhythmogenese im isolierten Insektennervensystem
… Funktion wurden unterschieden: "korreliert zum central pattern generator (CPG)", "Komponenten des CPG" und "verschaltend zu anderen Netzwerken" (z.B. Flug, Laufen, Exkretion u.a.). Besonders die VentIN4 und VentIN5 ergaben neue Einblicke in die Natur der ventilatorischen Rhythmogenesei bei …

Behavioural and neural studies of male singing and female phonotaxis behaviour in crickets
… the forewings to generate sound pulses and song patterns. The central command for singing is controlled by the brain. The song structure is under control of the abdominal central pattern generator (CPG) and acts as a behavioural barrier to prevent courtship with females of closely related …

Design of flexible actuators using electro-active polymers and CPG-based control strategies
… analyzed. Further, mathematical modelling for Central Pattern Generators (CPGs) is presented. The condition for phase synchronization of coupled single chain oscil-lators is derived and various techniques for pattern generation using oscillator network are studied. Finally, octopus based …

Exploiting the Intrinsic Embodied Dynamics for Adaptive Robotic Behaviors
… the emergence of self-organization and adaptive pattern transition behaviors within a piano-playing context. The human upper-limb coordinate is studied through real-world physiological experiments and simulations. For a simulated pianist, the coupling between the controller, body, and environment …

An investigation into the role of cannabinoid and group 1 metabotropic glutamate receptors in the control of rhythmic locomotion in hatchling Xenopus Laevis
… G-protein coupled receptors (GPCRs) in the central nervous system (CNS) and its function has not been confirmed in Xenopus laevis tadpoles. Debate and research are still ongoing as to how CB1 can be targeted to improve disease outcomes and the extent of its effect in vivo. <br/><br/>The …
