It belongs to the DM1 posterior hemilineage (Nern et al., 2025). It receives input in the ipsilateral gorget, vest, superior posterior slope, inferior posterior slope, flange and cantle, the contralateral medulla serpentine layer, medulla layer M8, antennal mechanosensory and motor center, gorget, vest, posterior lateral protocerebrum, inferior clamp, superior posterior slope, inferior posterior slope and cantle, and the gnathal ganglion, inferior bridge and saddle (Nern et al., 2025). It sends output to the contralateral medulla serpentine layer, medulla layer M8 and medulla layer M9 (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There is one of these cells per hemisphere (Nern et al., 2025). fly_anatomy.ontology MeVC4b FBbt:20001884 VFB:FBbt_20001884 cM16 PS129 Cell type identified in multiple EM datasets (Scheffer et al., 2020; Schlegel et al., 2024; Dorkenwald et al., 2024; Nern et al., 2025). Synapse locations are given where each cell of this type in neuprint has at least 10 connections. Hemilineage information from neuprint, though original source not clear. Other information from Nern et al. (2025) supplements. bilateral
