Representative images of the amyloid-β plaque load in the brain of a 12-month-old AβPP-PS1 mouse.

<p>A: The Aβ plaque load was quantified in the prelimbic area at level +1.98 up to +1.78 anterior to bregma, B: in the anterior cingulate gyrus at level +1.10 up to +0.86 anterior to bregma, and C: in the dentate gyrus (DG), CA1 and CA3 areas of the hippocampus at level −2.18 up to −2.46 posterior to bregma, using one appropriate section per animal. Images were taken using a 2.5× objective. Scale bar = 500 µm.
