General Information
Term ITP and CRY expressing LNd neuron ID (Ontology) FBbt:00047189 (Fly Anatomy)
Definition LNd neuron of the adult brain characterized by the expression of ion transport peptide (ITP) and cryptochrome (CRY) (Schubert et al., 2018). From the cell body in the anterior ventrolateral protocerebrum (AVLP), the neuron projects medially around the anterior optic tract (AOT) and dorsally along the surface of the lateral horn (LH) (Schubert et al., 2018). At the posterior surface of the LH, the neuron branches (Schubert et al., 2018). One main branch projects towards the medulla, via the posterior lateral protocerebrum (PLP) and the accessory medulla (AME), with extensive further branching (Schubert et al., 2018). The other main branch innervates the superior neuropils (Schubert et al., 2018). Projections from both hemispheres overlap in the superior medial protocerebrum (SMP) (Schubert et al., 2018). There is one of these cells per hemisphere (Schubert et al., 2018).[ FlyBase:FBrf0238313 ]
Also Known As"ITP and CRY positive LNd neuron" ; "ITP expressing LNd neuron" ; "ITP positive LNd neuron" (for all, see Synonyms field below)
CommentPossible equivalence with 'extra LNd neuron', as both have a large cell body compared to other LNds (FBrf0238313 and FBrf0191052).
