transmedullary neuron Tm2 [FBbt_00003790]
Transmedullary narrow field neuron that has its main dendritic arborization in medulla layer M2 (Ting et al., 2014), where it receives input from lamina monopolar neuron L2 (Takemura et al., 2011), and additional postsynaptic terminals in M4-M5, where it receives input from lamina monopolar neuron L4 (Takemura et al., 2011). It has presynaptic terminals in layers M3, M4 and M9 (Fischbach and Dittrich, 1989; Takemura et al., 2011). Its axon follows the posterior edge of its cognate medulla column (Ting et al., 2014), then crosses the second optic chiasma to terminate in lobula layers 1 and 2 (Fischbach and Dittrich, 1989). In layer 1 it outputs to T neuron T5 (Shinomiya et al., 2014). It is a cholinergic neuron (Varija Raghu et al., 2011; Gao et al., 2008; Takemura et al., 2011). The neurotransmitter has been assessed by co-labelling cells with a P{Cha-GAL4.7.4} driver [FBtp0014830] and an anti-ChAT antibody (Varija Raghu et al., 2011), by using a Cha-GAL4.DBD [FBtp002350] (Gao et al., 2008) and by neurotransmitter was assessed by single cell RT-PCR measurement of choline acetyltransferase (FBgn0000303) expression (Takemura et al., 2011). Connectivity in the medulla was extrapolated from serial EM of 3 columns from a single sample (Takemura et al., 2008) or from 7 columns (Takemura et al., 2013). Connectivity in the lobula was assessed by serial section electron microscopy of a single column (Shinomiya et al., 2014).
