Tm39
ID: FBbt_00053406
Transmedullary neuron that receives most of its input in around 5 columns of medulla layers M4, M6 and M7-M8, where it also has a small number of presynapses in each innervation region (Nern et al., 2025). It crosses the second optic chiasm and has mixed pre- and post-synapses in around 3 columns of lobula layers 5A-5B (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Nern et al., 2025). There are around 200 of these cells per hemisphere (Nern et al., 2025).
Mapped to the Matsliah et al. (2024) Tm7 type, but given a new name in Nern et al. (2025), indicating that it may not be Tm7. Identified in EM and LM in Nern et al. (2025).
