Axonal terminals of multi-glomerular ORNs can be associated with similarly tuned glomeruli

(A) Maximum intensity projection of the lateral olfactory bulb showing three ORN axons (magenta) with terminals (arrowhead, asterisk, cross) connected to postsynaptic glomerular neuropil (color-coded by responsiveness to single amino acids, H, red; K, green; R, blue; W, yellow; F, gray).

(B) Individual imaging planes of the surveyed volume with their axon terminals (arrowhead, asterisk, or cross) and associated glomeruli highlighted. Scale bar equals 25 µm. Lower panels show a higher magnification of axon terminals (dashed white rectangles). Scale bar equals 10 µm.
