What feeds the moonwalker descending neuron

Presynaptic partners of MDN (FBbt:00111308), from VFB's precomputed connectivity for one MDN in each of two independent volumes — male CNS v0.9 MDN_R (891 partner rows) and FlyWire LAL.GNG.12 (359). Numbers are per-cell synapse weights, not class totals. Click any panel to open that neuron in the VFB 3D viewer.
