Central pattern generator
Central Pattern Generator
The Central Pattern Generator (CPG) is a biological neural network that produces rhythmic patterned outputs without requiring rhythmic sensory or central input. It is involved in controlling locomotion and other rhythmic behaviors.
Pronunciation
Central Pattern Generator: /ˈsɛntrəl ˈpætərn ˈdʒɛnəreɪtər/
Etymology
The term "Central Pattern Generator" is derived from its function and location. "Central" refers to its location in the central nervous system, "Pattern" refers to the rhythmic patterns it produces, and "Generator" refers to its role in generating these patterns.
Function
Central Pattern Generators are responsible for the rhythmic motor patterns that control locomotion, such as walking or swimming, in many animal species. They are also involved in other rhythmic activities such as breathing and swallowing.
Location
Central Pattern Generators are located in the spinal cord and brainstem, which are parts of the central nervous system.
