Increased total tau and phosphorylated tau species (Thr181, Ser199, Thr231) in the amygdala and hippocampus starting at three months.


Spatial memory deficits starting at five months by the Morris water maze. Olfactory deficits at five months indicated by the buried food test. No motor deficits (by rotarod, beam walk) or depressive behavior as indicated by the forced swim test.
