General Information
Term larval A02m neuron ID (Ontology) FBbt:00111248 (Fly Anatomy)
Definition Larval interneuron of the A02m group that is early-born in the NB2-1 Notch OFF primary hemilineage (Mark et al., 2021). Its soma is located in the ventral cortex region close to the medial part of the neuromere. It is a small neuron that receives input from the abdominal dorsal multidendritic neuron ddaC (Ohyama et al., 2015). Its soma is more dorsally-located than that of the A02n neuron (Ohyama et al., 2015).[ FlyBase:FBrf0228257 FlyBase:FBrf0233076 FlyBase:FBrf0249021 ]
Also Known As "larval pseudolooper-3 neuron"
Comment Listed as PMSI in Mark et al. (2021) supplement, but lacks characteristic dorsal loop (Zwart et al., 2016) and not included in PMSI group by Kohsaka et al. (2019) - FBrf0242656. Supplements of Mark et al. (2021) and Zarin et al. (2019) say these, or the A02n neurons, may be the mCSI neurons.
