Sequential actions: effects of upcoming perceptual and motor tasks on current actions.

abstract：:The amyloid precursor protein (APP) has a pivotal role in pathogenesis of Alzheimer's disease (AD) via its beta- and gamma-secretase-derived cleavage products--the A-beta peptides. An alternative processing pathway provided by the alpha-secretase prevents formation of those toxic peptides and gives rise to the neurotr...
