transmedullary neuron Tm5c [FBbt_00110074]
Subtype of the transmedullary neuron Tm5. It extends multiple fine dendritic processes that span around eight medulla columns in the M1, M3 and M6 layers. Its axon often bifurcates in lobula layer 4 to terminate in layers 4 to 6. Arbors are found both in columns that contain the photoreceptor axons of yellow and pale ommatidia. It receives input from the photoreceptor cell R8, mostly from terminals in layer M3, but also in M1 and M2, and from the distal medullary amacrine neuron Dm8 in layer M6 (Karuppudurai et al., 2014). It provides input to the lobula intrinsic neuron Li4 via many synapses (Lin et al., 2016). It differs from the subtypes Tm5a and Tm5b by its arborization pattern by arborizing in medulla layer M1. It is a glutamatergic neuron (Gao et al., 2008; Karuppudurai et al., 2014). The neurotransmitter was assessed in cells labelled with a glutamate GAL4 driver P{GawB}vGlut[OK371] [FBti0076967] (Gao et al., 2008), RT-PCR and by immunohistochemistry (Karuppudurai et al., 2014). Connectivity inferred from GRASP experiments (Karuppudurai et al., 2014; Lin et al., 2016), from EM reconstructions from a single EM section (inferred by curator to be Tm5c subtype based on evidence from other studies) (Gao et al., 2008) or from double-labeling EM (Lin et al., 2016).
