Figure 5: Thionin-stained histological section at the level of the lateral geniculate nuclei.

(a) Whole section. Scale bar, 1 cm. (b,c) Higher-magnification cross-sectional image of the dentate gyrus of the spared hippocampus. The fimbria is visible below the lateral geniculate nucleus. Scale bar, 1 mm. (d,e) × 20 magnification image of neurons in the CA4 region of the hippocampus (in the location of the box). Scale bar, 50 μm. PrG, precentral gyrus; PL, parietal lobe; CG, cingulate gyrus; LV, lateral ventricle; cc, corpus callosum; fx, fornix; Th, thalamus; TL, temporal lobe; LG, lateral geniculate nucleus; RN, red nucleus; SN, substantia nigra; DG, dentate gyrus; fi, fimbria.
