Its soma is found ventrolaterally and it extends dorsally, then medially, crossing the midline and terminating close to it (Zwart et al., 2016). Its postsynapses are mainly ipsilateral and its presynapses are mainly contralateral (Zwart et al., 2016). It outputs onto transverse muscle motor neurons and is required for the normal asynchrony in contraction between the transverse and longitudinal muscles during locomotion (Zwart et al., 2016). iIN-1 Renamed from A14a to A14a3 in Mark et al. (2021) based on catmaid skid. bilateral
