Figure 1From: Aging increases microglial proliferation, delays cell migration, and decreases cortical neurogenesis after focal cerebral ischemiaEffect of aging on infarct development. Infarct size was determined by MRI (2 days) and Nissl (7 days) after MCAO in young (2 to 3 months) and aged (13 to 14 months) mice after proximal (A) and distal (B) occlusions (see Methods). Data are mean ± SD, n = 8, *P < 0.05. MCAO, middle cerebral artery occlusion.Back to article page
