behavior/neurological
• in a simplified Morris water maze test, 20-month-old mice show a more severe spatial memory deficit with poorer escape learning during training trials and significantly less time spent in the target quadrant during the probe trial relative to age-matched transgenic mice wild-type for Apmap

nervous system
• 9-month-old mice show a 20 +/- 4 % increase in cerebral Abeta1-40 peptide levels associated with a 24 +/- 5 % increase in the hippocampal Abeta plaque area relative to age-matched transgenic mice wild-type for Apmap

homeostasis/metabolism
• 9-month-old mice show a 20 +/- 4 % increase in cerebral Abeta1-40 peptide levels associated with a 24 +/- 5 % increase in the hippocampal Abeta plaque area relative to age-matched transgenic mice wild-type for Apmap
