Its dendritic arborization occupies the intermediate domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve fasciculating with the ISNb nerve branch. Its soma is located in the segment anterior to the muscle it innervates (Landgraf et al., 1997). The VO1 neuron found in the metathoracic neuromere switches muscle targets during metamorphosis to become adult persistent motor neuron 30-Ib (Banerjee et al., 2016). The VO1 cells of (at least) abdominal neuromeres 1-3 die during metamorphosis (Banerjee et al., 2016). larval abdominal intersegmental nerve motor neuron larval intersegmental nerve branch ISNb of A1-7 larval anterior intersegmental nerve root of A1-7 larval lateral A1-7-innervating ISN motor neuron
