Central pattern generators
What are they? Central pattern generators (CPGs) are relatively small, relatively autonomous groups of neurons (neural networks) that produce patterned, rhythmic neural outputs that drive rhythmic behaviours. In addition to generating boring behaviours like walking, CPGs are also responsible for dancing, chewing, swallowing, suckling, copulation and orgasm — all the things that make life worthw...
متن کاملCommentary/Selverston: Central pattern generators
and ion channels must be functionally described in order to obtain a full understanding of a CPG, we will not have a detailed, mechanistic explanation for some considerable length of time. A complete compilation of the detailed molecular biophysics of neurons will long remain the "quark" of cellular and integrative neurobiology. The most disturbing feature of the Selverston paper is its pessimi...
متن کاملRethinking central pattern generators: A general approach
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. We demonstrate our approach by generating a novel model of lamprey locomotion. However...
متن کاملCentral pattern generators for bipedal locomotion.
Golubitsky, Stewart, Buono and Collins proposed two models for the achitecture of central pattern generators (CPGs): one for bipeds (which we call leg) and one for quadrupeds (which we call quad). In this paper we use symmetry techniques to classify the possible spatiotemporal symmetries of periodic solutions that can exist in leg (there are 10 nontrivial types) and we explore the possibility t...
متن کاملCentral Pattern Generators Deciphered by Molecular Genetics
Central pattern generators (CPGs) are localized neuronal networks that have the ability to produce rhythmic movements even in the absence of movement-related sensory feedback. They are found in all animals, including man, and serve as informative model systems for understanding how neuronal networks produce behavior. Traditionally, CPGs have been investigated with electrophysiological technique...
