Hierarchical reinforcement learning with central pattern generator for enabling a quadruped robot simulator to walk on a variety of terrains [PDF]

open access: yesScientific Reports
We present a data-driven deep reinforcement learning (DRL) method for the optimization of a hierarchically structured control policy that includes the central pattern generator.

A central pattern generator approach to footstep transition for biped navigation

open access: yesInternational Journal of Advanced Robotic Systems, 2017
Existing sampling-based footstep planning method for biped navigation used an intermediate static posture for footstep transition. However, when adopting this approach, the robot is sensitive to modeling error and external environments, and also the ...

Driving respiration: The respiratory central pattern generator

open access: yesClinical and Experimental Pharmacology and Physiology, 1998
1, The central pattern generator (CPG) for respiration is located in the brainstem and produces rhythmic synaptic drive for motoneurons controlling respiratory muscles. Based on respiratory nerve discharge, the respiratory cycle can be divided into three

Potential role of a ventral nerve cord central pattern generator in forward and backward locomotion in Caenorhabditis elegans [PDF]

open access: yesNetwork Neuroscience, 2018
C. elegans locomotes in an undulatory fashion, generating thrust by propagating dorsoventral bends along its body. Although central pattern generators (CPGs) are typically involved in animal locomotion, their presence in C.

Organelle calcium-derived voltage oscillations in pacemaker neurons drive the motor program for food-seeking behavior in Aplysia

open access: yeseLife, 2021
The expression of motivated behaviors depends on both external and internally arising neural stimuli, yet the intrinsic releasing mechanisms for such variably occurring behaviors remain elusive. In isolated nervous system preparations of Aplysia, we have

Rethinking central pattern generators: A general approach [PDF]

open access: yesNeurocomputing, 2000
Abstract Central pattern generators (CPGs) have traditionally been modeled as sets of coupled bistable oscillators (Marder and Calabrese, Physiol. Rev. 76(3) (1996) 687–717). We present a framework for constructing models which avoid the shortcomings of these traditional models, while remaining biologically plausible.

The generation of antiphase oscillations and synchrony by a rebound-based vertebrate central pattern generator [PDF]

open access: yes, 2014
Many neural circuits are capable of generating multiple stereotyped outputs after different sensory inputs or neuromodulation.We have previously identified the central pattern generator (CPG) forXenopustadpole swimming that involves antiphase ...

Symmetry-breaking in a rate model for a biped locomotion central pattern generator [PDF]

open access: yes, 2014
The timing patterns of animal gaits are produced by a network of spinal neurons called a Central Pattern Generator (CPG). Pinto and Golubitsky studied a four-node CPG for biped dynamics in which each leg is associated with one flexor node and one ...
