General Information
Term pCC neuron ID (Ontology) FBbt:00001448 (Fly Anatomy)
Definition Interneuron that is born from the first GMC to bud from neuroblast NB1-1 (GMC1-1a) and is part of the Notch ON hemilineage (Skeath and Doe, 1998). Its large, round cell body is located just posterior, medial and ventral to its sibling, the MN-DA1 (aCC) motor neuron (FBbt:00001447). It extends a neurite anteriorly along one of the longitudinal fascicles (Doe et al., 1988). It expresses even-skipped (Manning et al., 2012).[ FlyBase:FBrf0048756 FlyBase:FBrf0058118 FlyBase:FBrf0064795 FlyBase:FBrf0102831 FlyBase:FBrf0219785 ]
Also Known As "posterior corner cell" ; "sibling of aCC"
