These neurons have less extensive arborization (layers 2-4) in their fan-shaped body column than their FR1 counterparts (Scheffer et al., 2020; Hulse et al., 2021). There are 18 of these neurons per fan-shaped body, following a nine-column organization (Hulse et al., 2021). VFB:FBbt_00051236 FBbt:00051236 fly_anatomy.ontology FR2
