General Information
Term larval excitatory interneuron eIN-5 ID (Ontology) FBbt:00111734 (Fly Anatomy)
Definition Larval excitatory interneuron (eIN) (Zwart et al., 2016) that is late-born in the NB7-1 Notch ON primary hemilineage (Mark et al., 2021). Its primary neurite enters the neuromere ventrolaterally and extends to the most dorsal region close to the midline (Zwart et al., 2016). It has relatively ventral postsynaptic sites and its more dorsal parts are mostly presynaptic (Zwart et al., 2016). It outputs onto the ipsilateral longitudinal motor neuron MN-LO1 (Zwart et al., 2016).[ FlyBase:FBrf0231611 FlyBase:FBrf0233076 FlyBase:FBrf0244727 FlyBase:FBrf0249021 ]
Also Known As "eIN-5" ; "larval A03a4 neuron"
Comment These neurons were identified in one EM reconstruction of the full CNS of a 6h old first instar larva. Neurotransmitter identified by antibody staining (Zwart et al., 2016).
