larval Jaam2 neuron

ID: FBbt_00111657

Interneuron of the larval ventral nerve cord (Heckscher et al., 2015 that is relatively late-born in the NB5-2 Notch OFF primary hemilineage (Mark et al., 2021. The primary neurite extends into the neuropil forming one arbor that bifurcates and extends anteriorly and posteriorly (Heckscher et al., 2015. One neurite crosses the midline and forms an arbor that extends anteriorly in a circular manner (Heckscher et al., 2015. It receives strong input from proprioceptive multidendritic neurons and outputs onto Jaam1 (Heckscher et al., 2015. There is one of these neurons per hemineuromere (Heckscher et al., 2015. (Mark et al., 2021, Heckscher et al., 2015)

These neurons were identified in two EM reconstructions: one of the full CNS of a 6h old first instar larva, and another of abdominal segment 3 of a 12-24h old first instar larva. Only bilateral connections are reported. The number of identified input synapses in A1 was the following (number in brackets left/right): from ddaD/ddAE/dda1 (34/25), from vbp/vdap (21/32). The number of identified output synapses was the following (number in brackets left/right): to Jaam1 (13/23). It is still not known if the pattern of connections is the same in the other abdominal segments (Heckscher et al., 2015. HMD2 and A12g synonyms from catmaid.
