behavior/neurological
• at 14 months of age, mutants are impaired in a passive avoidance learning test, with mice not avoiding the corners as much as controls during the acquisition phase or 24 hours later
|
• at 14 months of age, mutants require a longer time to habituate the corner visit response when placed inside the IntelliCage environment
|
• in the object recognition task, mutants explore the objects more during the sample phase
|
• young mutants show less exploratory behavior than controls during the initial adaptation period to the IntelliCage, showing a lower number of corner visits and visits with licks
|
• mutants perseverate in place preference extinction test at 4 and 14 months of age
|
• mice show lower water consumption under basal conditions at 4 months, but not 14 months, of age
|
• when a novel stimulus (smell at 4 months or aversive air-puffs at 4 months and 14 months) is presented in the familiar environment of IntelliCage, mutants do not inhibit their approaches to the corners as controls do, indicating behavioral disinhibition
|
• mutants repeat in visiting previously rewarded corners whereas controls are less likely to do so, indicating lower alternation rates and stereotypy
|
growth/size/body
• reduction in body weight, with the difference in average body weight being 14.8% at 4 months and 27% at 10 months
|
homeostasis/metabolism
• mice exhibit extensive plaque pathology at 17 months of age
|
nervous system
• mice exhibit extensive plaque pathology at 17 months of age
