General Information
Term larval mushroom body input neuron l1 ID (Ontology) FBbt:00047968 (Fly Anatomy)
Definition Larval neuron that has postsynapses in the basocentral compartment (lateral accessory lobe) and presynapses in the mushroom body lateral appendix (Saumweber et al., 2018). It the first instar, it additionally innervates the lower (V1) region of the vertical lobe (Eichler et al., 2017). It is neither octopaminergic nor dopaminergic (Eichler et al., 2017). It is synapsed by MBON-q1, FBN-2, FBN-24, FBN-25 and FBN-27 (Eschbach et al., 2020). It develops from a BLVa neuroblast (Saumweber et al., 2018), then trans-differentiates into a lateral accessory lobe-bilateral crepine neuron (Truman et al., 2023).[ FlyBase:FBrf0236359 FlyBase:FBrf0238440 FlyBase:FBrf0245294 FlyBase:FBrf0255928 ]
Also Known As "MBE19" ; "MBIN-l1"
Comment Lineage given as BLVa3/4 in Saumweber et al. (2018). MBE19 synonym from catmaid.
