N normal phenotype
behavior/neurological
• retention is reduced in passive avoidance tests involving electric shock training to prevent movement from a lighted area to a dark chamber
• retention of spatial memory in T-water maze tests declines as early as 3 months after acquisition, faster than for transgenics alone
• acquisition of spatial memory in T-water maze tests is normal

nervous system
• lower rate of plaque deposition at 3 and 6 months of age but equivalent to controls at 9 months
• higher brain levels of Abeta1-42

homeostasis/metabolism
• lower rate of plaque deposition at 3 and 6 months of age but equivalent to controls at 9 months
• higher brain levels of Abeta1-42
