General Information
Term pacemaker neuron ID (Ontology) FBbt:00006048 (Fly Anatomy)
Definition Neuron that supports clock-gene oscillations under light:dark cycles or constant conditions, and participates in control of the diurnal rhythm of the organism. Molecular oscillation of Period and Timeless expression levels are central to the molecular mechanism of pacemaking, and are key criteria for defining a pacemaker cell (Kaneko, 1998).[ FlyBase:FBrf0093121 FlyBase:FBrf0105254 FlyBase:FBrf0195358 ]
Also Known As"clock neuron"
