FR2 [FBbt_00051236]

Adult fan-shaped body 1 column-rubus (FR) neuron with little within-type connectivity in each rubus (Hulse et al., 2021). 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).
