Its primary neurite branches in the M2 layer, in the same sublayer as Dm14 and Dm19, and often shows bifurcations that cover separate medulla regions. It is a very large cell, with its arbor covering up to half of the whole M2 layer. The arbor is located in a intracolumnar position. There are 5 Dm17 neurons per hemisphere.
