N normal phenotype
behavior/neurological
• six month old mice have poor context discrimination although contextual conditioning is normal
• six month old mice much slower to learn the platform position in a hidden platform Morris water maze (Motor coordination normal)

nervous system
• six month old mice are deficient in the early phase of long term potentiation although there is no disruption of synaptic transmission or presynaptic plasticity
