A Schematic of the D. melanogaster CNS with the mushroom bodies highlighted in dark gray. Representative examples of an LVIN (PLP095) and VPN (CB0156). Anterior view. Scale bar, 30 μm. B Mushroom body volume with visual Kenyon cell subtypes overlaid. dACA, dorsal accessory calyx, vACA, ventral accessory calyx. (B’) KCγ-d, green receives input in the vACA. (B”) KCαβ-p, purple, receives input in the dACA. Scale bar, 15 μm. C Proportion of KCγ-d visual inputs that are either VPNs (green) or LVINs (gray). D Proportion of visual synapses onto KCγ-d that are either from VPNs or LVINs. E Ranking all VPN and LVIN inputs to KCγ-d by their total synaptic contribution to KCγ-d’s. F Proportion of KCαβ-p visual inputs that are either VPNs (purple) or LVINs (gray). G Proportion of visual synapses onto KCαβ-p that are either from VPNs or LVINs. H Ranking all VPN and LVIN inputs to KCαβ-p by their total synaptic contribution to KCαβ-p’s. I Proportion of direct visual inputs and LVINs that are either specific to or shared among KCγ-d and KCαβ-p. All data in panels B-I examine connectivity to KCs in the left hemisphere, using a ≥ 5 synapse threshold. Source data are provided as a Source Data file.
