larval abdominal 1 down and back neuron [FBbt_00047727]
Larval down and back neuron of abdominal neuromere 1. it is a somatosensory interneuron that arborizes in the nociceptive neuropil and receives input from all three class IV dendritic arborizing neurons. The majority of its other input is also from sensory neurons and the majority of its output is to premotor neurons. From a laterally-located cell body, it projects ventromedially to the nociceptive neuropil and arborizes profusely. A single process also projects back laterally and dorsally towards the cell body. It is involved in activating bending and rolling behavior in response to nociceptive stimuli, such as noxious heat. In a reconstructed L1 VNC EM volume, this neuron generally receives more than 7 percent of its postsynapses from each of the multidendritic arborizing neurons (vdaB, vdaa and ddaC), 45.5 percent from all three in total (Gerhard et al., 2017; Burgos et al., 2018). It receives 15 percent of its postsynapses (in total) from class III dendritic arborizing (mechanosensory) neurons (Burgos et al., 2018).
