Fluorescence images of the olfactory bulb and brain following i.n delivery of AdGFP. After intranasal delivery of AdGFP, mice were sacrificed at days 1, 3, 7 and 12 (one mouse/time point) and freshly harvested organs were subject to fluoroscopic imaging. Magnifications (zoom range): olfactory bulb ×25; brain ×7. The images are representative of three independent experiments.
