title: Effects of aging on NMDA and MK801 binding sites in mice.
abstract: [3H]MK801 binding was significantly reduced in three cortical and two subcortical regions in 30-month-old C57Bl mice, as compared to 3-month-olds. NMDA binding sites showed significant reductions with aging in sixteen of nineteen brain regions. These results suggest that, in a majority of cortical and hippocampal regions, decreases in binding to NMDA sites with aging may be due to factors other than cell loss.
