Its primary neurite extends into the M6 layer, and then turns back to project to M3B. The arbor is circular in shape, overlapping and covering around 15-20 columns. The arbor is located in a peripheral intracolumnar position. There are around 120 Dm12 neurons per hemisphere. They are glutamatergic (Davis et al., 2020).
