behavior/neurological

behavior/neurological phenotype ( J:192108 )

N • mice exhibit normal locomotor and exploratory activity (open field test), motor coordination (rotarod) and anxiety-related behaviors (elevated plus maze)

abnormal response to novelty ( J:192108 )

• mice exhibit no difference in the proportion of time exploring an object in a novel or familiar context unlike wild-type mice

• however, mice exhibit normal spatial learning and memory retention

nervous system
