nervous system
• mice begin to show increased activation of astrocytes at 24 months of age in the cerebral cortex and hippocampus
• mice begin to show increased activation of microglia at 12 months of age in the cerebral cortex and hippocampus
• mice exhibit a decrease in mature neurons in the hippocampal CA1 region at 24 months, but not 18 months of age
• mice show tangle-like inclusions in the hippocampal CA1 region and the retrosplenial region of the cerebral cortex at 24, but not 18, months of age
• levels of synaptic density in the hippocampal CA3 region begin to decrease at 6 months of age in the (pcl)/striatum lucidum 1 (sl1) area and at 24 months of age in the larger pcl/sl1/stratum lucidum 2 (sl2) area indicating that synapse loss begins from areas closer to the pcl
