Objective: The aim of this review was to synthesize, using random-effects model of meta-analysis, the link between dopaminergic system and Alzheimer’s disease. Methods: A detailed analysis protocol was registered at the PROSPERO database prior to data extraction (CRD42018110798). Electronic databases of PubMed, Embase, Web of Science, and Psyc-ARTICLES were searched up to December 2018 for […]

Several neural and non-neural factors contribute to individual differences in cognitive performance. Here we outline a sequence of vascular events where excessive transfer of arterial-pressure pulsatility damages hippocampal capillaries. We argue that the vascular alterations decrease the ability to sustain neural activity and thereby contribute to episodic-memory impairment in aging. Read Full Article (External Site) […]

A common assumption in theories of working memory is that a maintenance process – broadly referred to as rehearsal – is involved in keeping novel information available. This review evaluates the effectiveness of three forms of rehearsal: articulatory rehearsal, attention-based refreshing, and elaborative rehearsal. Evidence for the effectiveness of these strategies is surprisingly weak. Experimental […]
