N normal phenotype
nervous system
• at 12 and 17 months of age, females have significantly more plaques in the hippocampus compared to males; plaque load increases dramatically with age in mice, particularly in females

behavior/neurological
• poor retention latency exhibited in light-dark step through box
• escape latencies across trial blocks in left-right discrimination learning are elevated and decrease little in comparison to decreased escape latencies exhibited in controls
• required higher trials to reach criterion and committed more errors in comparison to controls
• increased duration of immobility in Porsolt forced swim test
• increased irritability in response to touch escape test as compared to control
• poor nest building ability in comparison to controls

homeostasis/metabolism
• at 12 and 17 months of age, females have significantly more plaques in the hippocampus compared to males; plaque load increases dramatically with age in mice, particularly in females
