Definition
A central pattern generator (CPG) is an assembly of neurons (neuronal network) that produces rhythmic activity without requiring phasic input signals and often drives the motor system and rhythmic muscle movements. Sensory feedback to a CPG circuit is the return signal from the sensory system in response to this rhythmic muscle movement, which conveys a continuous measurement of the output behavior to the CPG.
Detailed Description
Individual neural networks, such as CPGs, can generate rhythmic output patterns even in the absence of any phasic input. They drive vital behaviors such as breathing, swallowing, and chewing, as well as locomotion and saccadic eye movements, and often continue to function even in isolated nervous system...
