title: Development of central pattern generating circuits.
abstract: The networks that generate rhythmic motor patterns in invertebrates and vertebrates are ideal for studying the mechanisms by which functional circuits are formed during development. Rhythmic motor patterns and movements are seen embryonically, before they are needed for behavior; recent work suggests that activity in immature spinal cord networks is important for circuit formation and transmitter specification. Despite significant advances in describing the patterns of transcription factor expression in both invertebrate nervous systems and vertebrate spinal cord, a real understanding of how central pattern generators develop is hindered by our lack of knowledge of the organization of these circuits in adults.
