Lamina monopolar neuron l5
FBbt:00003725
A lamina monopolar neuron that hardly arborizes at all in the lamina, but forms a branched arborization in medulla layers M1 and M2 and a clump of terminals in M5. In the medulla, it forms strong reciprocal synaptic connections with monopolar lamina monopolar neuron L1 (Takemura et al., 2013). It also receives substantial input from L2 and C2 neurons and has many presynapses connecting to medullary intrinsic neurons Mi1 and Mi4, and to transmedullary neuron Tm3a (Takemura et al., 2013). It is a cholinergic neuron (Davis et al., 2020). There is usually one of these cells per optic column (Nern et al., 2025).
