General Information
Term larval A27a neuron ID (Ontology) FBbt:00111678 (Fly Anatomy)
Definition Neuron of the larval abdominal neuromere that is part of lineage 27. In each abdominal segment, the primary neurite bifurcates, with one branch arborizing dorsally and the other ventrally. It receives input from the GDL neuron (Fushiki et al., 2016). There is one of these neurons per hemisegment.[ FlyBase:FBrf0231611 ]
Comment These neurons were identified in a EM reconstruction of the full CNS of a 6h old first instar larva. The number of identified input synapses was the following (number in brackets left/right): from GDL (17/11) (Fushiki et al., 2016).
