General Information
Term larval excitatory interneuron eIN-4 ID (Ontology) FBbt:00111733 (Fly Anatomy)
Definition Larval excitatory interneuron (eIN) (Zwart et al., 2016) that is part of lineage 3. Its cell body is on the ventral rind and the primary neurite extends dorsally and anteriorly, with dorsal presynapses and slightly more ventral postsynapses, remaining ipsilateral (Schneider-Mizell et al., 2016; Zwart et al., 2016). It outputs onto several motor neurons (Zarin et al., 2019), including the longitudinal motor neuron MN-LO1 (Zwart et al., 2016) and the dorsal motor neuron (RP2; MNISN) (Schneider-Mizell et al., 2016). It receives input from A02b (Schneider-Mizell et al., 2016).[ FlyBase:FBrf0231328 FlyBase:FBrf0233076 FlyBase:FBrf0244727 ]
Also Known As "eIN-4" ; "larval A03a1 neuron"
