The mammalian central pattern generator for locomotion.
At the beginning of the 20th century, Thomas Graham Brown conducted experiments that after a long hiatus changed views on the neural control of locomotion. His seminal work supported by subsequent evidence generated largely from the 1960s onwards showed that across species walking, flying, and swimming are controlled largely by a neuronal network that has been referred to as the central pattern...
متن کاملComputational modelling of a Central Pattern Generator
Central Pattern Generators (CPGs) are small, rhythmically active networks, which control simple repetitive behaviours, in both vertebrates and invertebrates. Research on CPGs aims at understanding how the periodic pattern is generated and modulated, by investigating the intrinsic and synaptic properties of the component neurons. In this study, we present a mathematical, biophysically-realistic ...
متن کاملA Learning Model of a Periodic Locomotor Pattern by the Central Pattern Generator
Many basic locomotor patterns of living bodies are rhythmic, and oscillatory components of physical systems effectively contribute to the generation of the movement. The control signals for the basic locomotor patterns are generated by the central pattern generator (CPG), which is composed of collective neural oscillators, and the activity of the CPG is tightly synchronized with the movement of...
متن کاملModelling a Respiratory Central Pattern Generator Neuron in Lymnaea Stagnalis
Lymnaea stagnalis, often termed the great pond snail, is characterized in part by its ability to take in oxygen both cutaneously and aerially (via its rudimentary lung). The central nervous system of the Lymnaea is composed of a relatively small number of large, identifiable neurons. In 1990, Syed et al. [1] established that respiratory rhythmogenesis in the Lymnaea is controlled by a 3-neuron ...
متن کاملAsymmetric operation of the locomotor central pattern generator in the neonatal mouse spinal cord.
The rhythmic voltage oscillations in motor neurons (MNs) during locomotor movements reflect the operation of the pre-MN central pattern generator (CPG) network. Recordings from MNs can thus be used as a method to deduct the organization of CPGs. Here, we use continuous conductance measurements and decomposition methods to quantitatively assess the weighting and phase tuning of synaptic inputs t...
