Previous studies from our lab have shown that environmental enrichment in young rats results in improved learning ability and enhanced metabotropic glutamate receptor-dependent long term potentiation (mGluR-LTP) resulting from sustained activation of p70S6 kinase. Here we investigated whether 1-month environmental enrichment is sufficient to improve hippocampus-dependent learning and memory and enhance hippocampal LTP in 23–24 month old Fischer 344 male rats. Aged rats were housed in environmentally enriched (EE), socially enriched (SE), or standard housing (SC) conditions. We find that aged rats exposed to one month of environmental enrichment demonstrate enhanced learning and memory relative to standard housed controls when tested in the Morris water maze and novel object recognition behavioral tasks. Furthermore, we find that EE rats perform significantly better than SE or SC rats in the radial-arm water maze, and display enhanced mGluR5-dependent hippocampal LTP. Enhanced hippocampal function results from activity-dependent increases in the levels of mGluR5, Homer1c, and phospho-p70S6 kinase. These findings demonstrate that a short exposure of environmental enrichment to aged rats can have significant effects on hippocampal function.
