Its primary neurite branches in both the M1/M2 and M2/M3 boundary regions. The arbor is elongated along the dorsal-ventral axis, with higher arbor density located at the dorsal end of the cell. The arbor is located in a peripheral columnar position. There are around 100 Dm16 neurons per hemisphere.
