N normal phenotype
behavior/neurological
N
• mice exhibit normal novel object recognition after short- or long-term intertrial intervals
• following long-term intertrial intervals (ITI), mice exhibit impaired social recognition (SRE) compared with wild-type mice
• however, SRE is normal following a short-term ITI

nervous system
N
• mice exhibit normal motor cortex layer thickness and cell number
• in deeper layers
• mice exhibit reduced total apical dendrite length, surface and number of intersections compared with wild-type mice
• in deeper layers of the cortex
