Using Fluoro\u2010Jade C and monodansylcadaverine double\u2010staining, and electron microscopy we found the increment in autophagy after OGD\/RP was accompanied by increased autophagic cell death, and this increased cell death was inhibited by the specific autophagy inhibitor, 3\u2010methyladenine. The presence of large autolysosomes and numerous autophagosomes in cortical neurons were confirmed by electron microscopy. Autophagy activities were increased dramatically in the ischemic brains 3\u20137 days postinjury from a rat model of neonatal cerebral hypoxia\/ischemia as shown by increased punctate LC3 staining and BECN1 expression. <jats:bold>Conclusion:<\/jats:bold> Excessive activation of autophagy contributes to neuronal death in cerebral
