Its arbors span several columns, and may include columns outside of the DRA, though its non-DRA arbors are just proximal to M6, avoiding photoreceptor terminals (Kind et al., 2021). It has presynaptic sites in the small unit of the anterior optic tubercle, in a region distinct from the terminals of non-DRA MeTu neurons (Kind et al, 2021).
