CB3851 [FBbt_20007266]

Adult transmedullary neuron with its soma distal to the medulla (Nern et al., 2025). It is mainly postsynaptic, but also has presynapses, in around 5 columns of the medulla, with arbors mainly in M6, but also other layers from M3-M8 (Nern et al., 2025). It crosses the second optic chiasm and has mixed pre- and post-synapses in around 3 columns of lobula layer 5 (Nern et al., 2025). There are approximately 370-550 of these cells per hemisphere (Nern et al., 2025).
