General Information
Term DN1 neuron ID (Ontology) FBbt:00003629 (Fly Anatomy)
Definition DN (dorsal Period-expressing neuron of adult brain) whose cell body is located dorsal to the projections of the s-LNv Pdf neurons (FBbt:00003764). There are about 17 of these per cluster.[ FlyBase:FBrf0183981 FlyBase:FBrf0193849 ]
Also Known As "adult dorsal neuron 1" ; "adult dorsal neuron-1" ; "DN1"
Comment Can be distinguished from other clock neurons based on expression of glass (Abruzzi et al., 2022 - FBrf0234897).
