¹⁾Aβ40-1A, Alzheimer’s disease control group treated with amyloid-β protein 40-1 for placebo effect (1.8 μL ICV microinjection to hippocampus); Aβ40-1B, bilberry added control group; Aβ1-42A, Alzheimer’s disease (AD) group induced by amyloid-β protein1-42 (1.8 μL ICV microinjection to hippocampus); Aβ1-42B, bilberry added AD group.

²⁾Mice were allowed to have free access to diet and provided powered mixed diet based on AIN-76 formula including AIN-76 mineral and vitamin mixtures.
