Differential Influence of Amyloid-β on the Kinetics of Dopamine Release in the Dorsal and Ventral Striatum of Rats.

Dopaminergic dysfunction is a part of Alzheimer's disease pathology. The brain accumulation of amyloid-β of toxic form is a key link of the pathology, which, according to the literature, is also true for dopaminergic dysfunction. An increase in the amyloid-β level in the brain changes the maximum of the evoked dopamine release in the dorsal and ventral parts of the striatum of the experimental animals.
