General Information
Term larval excitatory interneuron eIN-2 ID (Ontology) FBbt:00111731 (Fly Anatomy)
Definition Larval eIN that is part of lineage 1 (Zwart et al., 2016; Burgos et al., 2018; Zarin et al., 2019) Notch ON (dorsal) primary hemilineage (Mark et al., 2021). Its soma is located ventrolaterally and its neurites extend contralaterally, then curve dorsally and medially back towards the midline (Zwart et al., 2016). A mainly presynaptic branch follows a more lateral route and terminates in the dorsal neuropil and a mostly postsynaptic branch follows a more medial route (Zwart et al., 2016). It outputs onto a specific subset of contralateral transverse motor neurons, including MN-LT1-4 and MN-DT1 (Zwart et al., 2016).[ FlyBase:FBrf0231327 FlyBase:FBrf0233076 FlyBase:FBrf0238464 FlyBase:FBrf0244727 FlyBase:FBrf0249021 ]
Also Known As "eIN-2" ; "larval A01c neuron" ; "larval A01c1 neuron"
Comment Referred to as A01c in Zwart et al. (2016) fig S2 (= A01c1 based on lack of ipsilateral dendrite). A01c1 and A01c2 have their names swapped in Mark et al. (2021) supplementary table (based on catmaid skid).
