The cell body fiber projects towards the anterior of the inferior neuropils and on the way there it bifurcates with one branch turning ventrally and terminating in the ventral complex (Tanaka et al., 2008). The second branch further branches in the crepine close to the beta lobe (Tanaka et al., 2008), with dendritic arborization (Aso et al., 2020). One fiber runs medially to the opposite hemisphere (Tanaka et al., 2008). Another turns ventrolaterally and arborizes in the basal segments of the gamma lobe (slice 2) and alpha' lobe (slice 1) (Tanaka et al., 2008; Li et al., 2020). The contralateral fiber innervates the same mushroom body regions (Li et al., 2020). The final branch arborizes in the superior medial protocerebrum (Tanaka et al., 2008), with dendritic arborization (Aso et al., 2014). There is one neuron of this type in each hemisphere (Aso et al., 2014; Li et al., 2020) and it develops from the larval DAN-d1 (Truman et al., 2023). It is involved in aversive learning and forgetting (Berry et al., 2018). Names are assigned according to the area of the mushroom body they arborize, as detailed in Tanaka et al. (2008). The PPL1 cluster was identified by TH immunostaining and using a TH-GAL4 driver (FBtp0020119) (Liu et al., 2012).
