It fasciculates with the intersegmental nerve, but unusually, innervates muscles in the same segment as its cell body (Landgraf et al., 1997, Landgraf et al., 2003). Its large soma is located at the extreme dorsal surface of the CNS above the junction of the anterior commissure and the longitudinal connective (Schmid et al., 1999). It expresses even-skipped (Manning et al., 2012). It is the first-born progeny of neuroblast NB4-2 and is found in thoracic and abdominal (A1-A9), but not gnathal, segments (Birkholz et al., 2013; Rickert et al., 2018).
