Figure 1.
Neuronal cell death only in CA1 of hippocampus. A shows the structure of the hippocampus. CA1-3: Cornu Ammonis 1-3, Or: oriens layer of CA1, Py: pyramidal cell layer of CA1, Rad: radiatum layer of CA1, Lmol: lacunosum-molecular layer of CA1, GD: dentate gyrus. B shows microscopic images of the hippocampus immunostained with an anti-NeuN antibody. On day14, NeuN+ cell reduction was observed in CA1 but not in CA2-3.
