Fig. 7From: The human olfactory system in two proteinopathies: Alzheimer’s and Parkinson’s diseasesNissl-stained coronal mosaic-reconstructed sections of the human frontal lobe illustrating olfactory structures (a, b, d, f, h). Panels a, b and h include pictures of tissue blocks from where sections were obtained. Dashed line in a points to the approximate location of the olfactory peduncle. High-power magnifications from framed areas in b, d and f are illustrated in c, e and g, respectively. Calibration bar: 5000 μm for a, b, d, f, h, 2500 μm for c, 1250 μm for e, 1000 μm for g.
