FR1 [FBbt_00051235]

Adult fan-shaped body 1 column-rubus (FR) neuron with strong all-all connectivity of neurons of this type within each rubus (Hulse et al., 2021). These neurons have more extensive arborization (layers 2-5) in their fan-shaped body column than their FR2 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).
