MAPT: Transgenic Alzheimer's Disease Increased total tau, and phosphorylated tau (Thr181, Ser199, Thr231) in amygdala and hippocampus starting at 3 months. Spatial memory deficits starting at 5 months (Morris water maze). Olfactory deficits at 5 months (Buried food test). No motor deficits (rota rod, beam walk) or depressive behavior (forced swim test).
