It receives most of its input in the ipsilateral posterior lateral protocerebrum, as well as the accessory medulla and lobula layer 1 (Dorkenwald et al., 2024; Schlegel et al., 2024; Nern et al., 2025). It sends output to the superior medial protocerebrum in both hemispheres, and the contralateral superior lateral protocerebrum (Dorkenwald et al., 2024; Schlegel et al., 2024). It also has pre-and post-synapses in the contralateral mushroom body calyx (Dorkenwald et al., 2024; Schlegel et al., 2024). There is one of these cells per hemisphere (Reinhard et al., 2022). It is cholinergic (Reinhard et al., 2024). aMe13 FBbt:00052758 VFB:FBbt_00052758 fly_anatomy.ontology l-CPDN3 l-CPDN3 Mapped to aMe13 in FlyWire Codex. adult cholinergic neuron bilateral
