Gene Microarrays in Hippocampal Aging

Male Fischer 344 rats aged 4 months (young, n=10), 14 months (mid-aged, n=10), and 24 months (aged, n=10) were trained sequentially on two tasks: Morris Spatial Water Maze (SWM) and Object Memory Task (OMT). The training/testing sequence lasted 7 d, and hippocampal tissue was collected 24 hr later. Training and testing occured on each day except for days 2 and 3 of the 7 d sequence.
