Stefan Schöneich and Berthold Hedwig Cellular basis for singing motor pattern generation in the field cricket (Gryllus bimaculatus DeGeer) Brain and Behavior 2
Crickets use species-specific song patterns for acoustic communication. The singing behavior is based on a genetically fixed motor rhythm driven by a central pattern generator circuit in the central nervous system (CNS). We anatomically identified and physiologically characterized individual interneurons of the singing network in the Mediterranean field cricket. The results also disclosed functional mechanisms underlying the rhythm generation and provide a starting point for comparative studies of the song pattern generator circuits in cricket species that produce very different song patterns.
