(2014), a further two were added by Li et al. (2020) due to similar morphology. The additional neurons are referred to as "MBON15-like", but still classed as MBON15 neurons (Li et al., 2020). Truman et al. (2023) say two per hemisphere - probably original two. MBON15 MBON-15 FBbt:00111010 A cholinergic mushroom body output neuron whose dendrites arborize unilaterally in alpha' lobe slice 1 (Aso et al., 2014), with thin dendritic branches projecting through the edge of the alpha' lobe slices 2 and 3 (Aso et al., 2014). Its axon projects to the contralateral hemisphere, sharing a tract with MBONs 16 and 17, terminating in the superior intermediate and lateral protocerebrum, and lateral horn (Aso et al., 2014). There are 4 neurons of this type in each hemisphere, forming two different connectivity patterns (Li et al., 2020). At least one of these subtypes comprises two DL1 (CP2) secondary neurons (Truman et al., 2023). VFB:FBbt_00111010 MBON-alpha'1 bilateral
