Tract-tracing and immunofluorescence experiments. Sagittal sections of the anterior olfactory bulb showing incoming rhodamine-labeled dextran-amine (RDA)-fibers from injections into the anterior olfactory nucleus (A–C), olfactory tubercle (D–I) and piriform cortex (J–L) showing a rhodamine-labeled dextran-amine (RDA) under epifluorescence (D,G,J) and confocal (A,B,C,E,F,H,I,K,L) microscopy. CR, calretinin; ePL, external plexiform layer olfactory bulb; GL, glomerular layer olfactory bulb; GrL, granular layer; iPL, internal plexiform layer olfactory bulb; MCL, mitral cell layer; MOB, main olfactory bulbs. Calibration bar for (A,B) 25 μm; C 10 μm; (D) 100 μm; (E,F) 200 μm; (G–L) 50 μm.
