General Information
Term extra LNd neuron ID (Ontology) FBbt:00100170 (Fly Anatomy)
Definition LNd neuron of the adult brain characterized by having a slightly larger nucleus and cytoplasmic area compared to the other LNd neurons.[ FlyBase:FBrf0191052 ]
Comment Rieger et al. (2006) comment that the extra LNd also stains more strongly for Period (FBgn0003068) and Timeless (FBgn0014396) compared to the other LNd neurons. Under constant light (LL) conditions, the extra LNd neuron is the only LNd neuron which shows significant Period and Timeless cycling. This neuron must belong to one of the other LNd subclasses. It is most likely equivalent to the ITP and CRY expressing LNd neuron, as this has the largest cell diameter among LNd neurons (Schubert et al., 2018 - FBrf0238313).
