Compared to the female DNp13 cell, it has more periesophageal and subesophageal arborization, but less extensive arborization of higher regions (Wang et al., 2020). It extends along the full length of the ventral nerve cord, reaching the abdominal neuromere, but with less extensive arborization in this region than the female DNp13 cell (Wang et al., 2020). There is one of these cells per hemisphere (Robinett et al., 2010; Lillvis et al., 2024). It is activated by the presence of females, but not males (Takayanagi-Kiya and Kiya, 2019). It is cholinergic (Lillvis et al., 2024).
