behavior/neurological
• mice are significantly impaired in Morris water maze tasks

nervous system
• high level of amyloid beta aggregates are found in brain at 12 months of age

homeostasis/metabolism
• in 12-month old brains, there is a 27% reduction in amyloid beta aggregates compared to transgenic mice that are wild-type for Bace1; there are no significant differences at 20 months
• in 12-month old brains, there is 37% reduction in percentage of brain volume occupied by amyloid beta deposits, but no difference at 20 months
• high level of amyloid beta aggregates are found in brain at 12 months of age
