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

Mathematical analysis and simulations of the neural circuit for locomotion in lamprey [PDF]

open access: yes, 2004
We analyze the dynamics of the neural circuit of the lamprey central pattern generator. This analysis provides insight into how neural interactions form oscillators and enable spontaneous oscillations in a network of damped oscillators, which were not ...

NeuroPod: a real-time neuromorphic spiking CPG applied to robotics [PDF]

open access: yes, 2022
Initially, robots were developed with the aim of making our life easier, carrying out repetitive or dangerous tasks for humans. Although they were able to perform these tasks, the latest generation of robots are being designed to take a step further ...

Invertebrate Central Pattern Generation Moves along [PDF]

open access: yesCurrent Biology, 2005
Central pattern generators (CPGs) are circuits that generate organized and repetitive motor patterns, such as those underlying feeding, locomotion and respiration. We summarize recent work on invertebrate CPGs which has provided new insights into how rhythmic motor patterns are produced and how they are controlled by higher-order command and modulatory

Semaphorin7A: its role in the control of serotonergic circuits and functional recovery following spinal cord injury

open access: yesNeural Regeneration Research, 2022
Serotonin is a monoamine neurotransmitter synthetized in various populations of brainstem neurons. In the spinal cord, descending serotonergic projections regulate postural muscle tone, locomotion and rhythm and coordination of movements via the Central ...

Sigmoid transition approach of the central pattern generator-based controller for the snake-like robot

open access: yesInternational Journal of Advanced Robotic Systems, 2017
Snake-like robots can perform various types of locomotion in the complex environments. In this article, a novel two-layered central pattern generator-based controller is proposed for controlling snake-like robots.

Conditions for multi-functionality in a rhythm generating network inspired by turtle scratching [PDF]

open access: yes, 2015
Rhythmic behaviors such as breathing, walking, and scratching are vital to many species. Such behaviors can emerge from groups of neurons, called central pattern generators, in the absence of rhythmic inputs.

A SpiNNaker Application: Design, Implementation and Validation of SCPGs [PDF]

open access: yes, 2017
In this paper, we present the numerical results of the implementation of a Spiking Central Pattern Generator (SCPG) on a SpiNNaker board. The SCPG is a network of current-based leaky integrateand- fire (LIF) neurons, which generates periodic spike ...

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 ...

Central Pattern Generator for Locomotion: Anatomical, Physiological and Pathophysiological Considerations

open access: yesFrontiers in Neurology, 2013
This article provides a perspective on major innovations over the past century in research on the spinal cord and, specifically, on specialized spinal circuits involved in the control of rhythmic locomotor pattern generation and modulation. Pioneers such
