Tm31 [FBbt_00053513]

Transmedullary neuron that spans around 5-10 columns in the medulla and lobula (Nern et al., 2025). In the medulla, it has pre-synapses in layer M7 and post-synapses mainly in layers M6-M8, with a smaller number in layers M2-M4 (Nern et al., 2025). In the lobula, it has inputs and outputs in layers 5A-6 in around 5-10 columns (Nern et al., 2025). Its soma is found distal to the medulla (Nern et al., 2025). It is predicted to be glutamatergic (Eckstein et al., 2024; Nern et al., 2025). There are around 55-60 of these cells on each side (Nern et al., 2025).
