Histological image of dentate gyrus in animals in group IDPAE (enlargement 400x). Neuron degradation states occur on a similar level like in Ammon’s horn and mainly concern pyramidal cells (1), whereas granular cells (2) show more advanced degenerative processes of neurons; in the lumen of capillary vessels, there are numerous erythrocytes visible in rouleau formation (1), which may indicate the presence of venostasis.
