DIN neurites overlap with projections from antennal hair field afferents in the GNG. All double labelings of antennal hair field afferents (HF, green) and DINs (magenta) were obtained in the same individuals. Scale bars, 50 μm. Ai, Projections of antennal hair field afferents and cONv in the deutocerebrum of the brain. For localization and orientation, see Figure 1D. Aii, Aiii, 10 μm thin stacks of the region indicated by the box in Ai, imaged at two different depths. Bi, Projections of antennal hair field afferents and the main cONv branches in the GNG. Bii, Biii, 10 μm thin stacks of the regions indicated in Bi, imaged at the same depth. Bii, Left hair field afferents and smooth cONv branch, left box in Bi. Biii, Right hair field afferents and cONv branch with bleb-like protrusions, right box in Bi. Ci, Projections of antennal hair field afferents and the main iONv branches in the GNG. Cii, 10 μm thin stack showing the region indicated by the box in Ci. D, Schematic of the projection sites of antennal hair field afferents and the main arborizations of cONv, iONv, and OFFv in the GNG.
