Histological analysis of CA1 region of the hippocampus demonstrates delayed neuronal death. Representative images of H&E demonstrate a lack of injury at 24 hours (A.) and large injury at 3 days (B.) as demonstrated by eosinophilic cytoplasm and pyknotic nuclei. Scale bar = 50um. Representative images of Fluoro-jade labeling is absent in the CA1 at 24 hours (C.) and intensely labeled at 3 days after CA/CPR. N=5-8. Scale bar = 50um
