Fig. 2: Direct visual inputs to KCγ-d neurons come from diverse optic lobe neuropils.

A Schematic of optic lobe neuropils and mushroom body in the left hemisphere. The same neuropils are present in the right hemisphere but are not highlighted here. Me, Medulla; aMe, Accessory Medulla; Lo, Lobula; MB, Mushroom Body. Scale bar, 50μm. B Proportion of KCγ-d VPN partners that originate from one of the 3 optic lobe neuropils in (A). C Proportion of VPN synapses onto KCγ-d by optic lobe neuropil origin. D Morphologies of the top three VPN classes from each neuropil that provide the most synaptic input to KCγ-d’s. Scale bars, 20 μm. E Proportion of synapses from each neuropil that come from the top 3 morphological types in (D). F Ranking of morphological VPN classes by total synaptic contribution to KCγ-d’s. G Percentage of KCγ-d’s contacted by each morphological VPN class (out of 147 KCγ-d’s in the left hemisphere). VPN classes are ordered on the x-axis as in (F) to show that classes making larger numbers of synapses also contact larger percentages of KCγ-d partners. Data in this figure examine connectivity to KCγ-d in the left hemisphere, using a ≥ 5 synapse threshold. Source data are provided as a Source Data file.
