Consistent connectivity by PNs between specific AL glomeruli and calyx glomeruli. (A) Generation of FLP-out clones in GH146-GAL4-expressing cells (shaded) by hsFLP expression labels different single PNs (example in green) including their projections in both AL and calyx. (B) Each pair of panels shows the same PN, labeled with mCD8::GFP (green), with presynaptic terminals in the calyx (Cx, upper panel of each pair) and dendritic arborizations in the AL (lower panel of each pair). Two preparations (left pair and right pair) are shown for each class of PN. Shown are projections of confocal sections, with total thicknesses between 3 and 10 μm. Calyx sections here and subsequently are viewed from a posterodorsal angle (Fig. S2), with anterior to the bottom and lateral to the left. In preparations with 2 labeled PNs, the designated glomeruli are highlighted by broken lines. cb, cell body.
