General Information
Term larval Handle-B neuron ID (Ontology) FBbt:00111243 (Fly Anatomy)
Definition Unpaired interneuron of the larval abdominal neuromere that is part of lineage 0. Its dendritic and axonal domains are located in the medial ventral nerve cord crossing the midline (Ohyama et al., 2015). It receives substantial input from mechanosensory chordotonal neurons, as well as limited input from the Basin neurons (Ohyama et al., 2015; Jovanic et al., 2016). This neuron feeds back to other local interneurons in the Basin circuit via inhibitory GABAergic connections (Jovanic et al., 2016).[ FlyBase:FBrf0228257 FlyBase:FBrf0233796 FlyBase:FBrf0239413 ]
Also Known As "fbLN-Hb" ; "larval A00b neuron"
Comment Originally mis-named as A00b2 by Ohyama et al. (2015) (FBrf0228257) - the correct synonym is A00b (FBrf0239413). Authors of FBrf0228257 and FBrf0233796 do not explicitly state which VNC segments this neuron exists in, therefore, subclasses may not be exhaustive.
