The cell body fiber ascends through the median bundle to the level of the gamma lobe before making a steep lateral turn and forming extensive axonal terminals in the crepine, superior medial protocerebrum and a few terminals in the superior intermediate protocerebrum (Tanaka et al., 2008; Aso et al., 2014). The main fiber further extends towards the vertical lobe and forms extensive dendrites in all strata of the alpha' lobe slice 2 (Tanaka et al., 2008). There is one of these cells per hemisphere (Aso et al., 2014; Li et al., 2020). It is a secondary FLAa2 (BAmas1) neuron (Truman et al., 2023). It plays an important role in retrieval of alcohol-associated memory (Scaplen et al., 2020). MB-V4 neuron VFB:FBbt_00100239 FlyBrain_NDB:10464 Tanaka et al. (2008) comment that there is a small possibility of interconnectedness between MB-V3 and MB-V4 because thin fibers are occasionally found connecting the two neuronal projections. Truman et al. (2023) claim two per hemisphere. MBON13 mushroom body vertical lobe arborizing neuron 4 FBbt:00100239 MBON-alpha'2 mushroom body alpha' lobe slice 2
