In Alzheimer disease (AD), which is the most common cause of dementia, the underlying
disease pathology most probably precedes the onset of cognitive symptoms by many years …

Long-term potentiation in the hippocampus can be enhanced and prolonged by
dopaminergic inputs from midbrain structures such as the substantia nigra. This improved …

Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterized by
