nervous system
• brains of aged mice exhibit lower levels of fully phosphorylated tau and show sarcosyl-insoluble tau aggregates
• however, mice do not show formation of neurofibrillary tangles in neurons and do not exhibit synaptic loss in the entorhinal cortex
|
• density of neurons in temporal area, entorhinal cortex, lateral amygdala, and basolateral amygdala is reduced in aging mice indicating neuronal loss
• neuron loss is seen in various brain regions that also exhibit sarcosyl-insoluble tau aggregates
|
behavior/neurological
N |
• mice exhibit normal behavior in the Morris water maze, indicating no memory impairment and the ability to form place memories
