General Information
Term larval A14h neuron ID (Ontology) FBbt:00111683 (Fly Anatomy)
Definition Segmentally-repeated cholinergic premotor neuron of the larval ventral nerve cord (Burgos et al., 2018; Zarin et al., 2019) that is late-born in the NB4-1 Notch OFF primary hemilineage (Mark et al., 2021). Its primary neurite enters the neuromere dorsally, extends ventrally and arborizes, then extends anteriorly, remaining ipsilateral (Fushiki et al., 2016; Kohsaka et al., 2019). It is cholinergic and is active during backwards fictive locomotion (Kohsaka et al., 2019). Its input synapses are mainly in the same hemisphere as the soma and its output synapses, including to premotor neurons, are mainly in the next anterior neuromere (Kohsaka et al., 2019).[ FlyBase:FBrf0231611 FlyBase:FBrf0238464 FlyBase:FBrf0242656 FlyBase:FBrf0244727 FlyBase:FBrf0249021 ]
Also Known As "Ifb-Bwd" ; "intersegmental feedback neuron in backward propagation"
Comment Renamed from A27k to A14h in Mark et al. (2021) (based on catmaid skid), probably due to lineage reassignment.
