Alpha phase dynamics predict age-related visual working memory decline
Alpha oscillations (7-14Hz) are modulated in response to visual temporal and spatial cues. However, the neural response to alerting cues is less explored, as is how this response is affected by healthy aging. Using scalp EEG, we examined how visual cortical alpha activity relates to working memory performance. Younger (20-30 years) and older (60-70 years) participants were presented with a visu...
متن کاملInvolvement of hippocampal synaptic plasticity in age-related memory decline.
This article examines the functional significance of Ca(2+)-dependent synaptic plasticity in relation to compromised memory function during aging. Research characterizing an age-related decline in memory for tasks that require proper hippocampal function is summarized. It is concluded that aged animals possess the mechanisms necessary for memory formation, and memory deficits, including rapid f...
متن کاملAge-related memory decline: current concepts and future directions.
The effect of age on memory and the brain has been the focus of many studies. Results have identified critical questions that need to be addressed to further our understanding of age-related memory decline: Is cognitive decline diffuse or selective? Where does memory decline localize to anatomically? Does decline represent an abnormal state? What are the causes of memory decline? What level of ...
متن کاملPupillary responses and memory-guided visual search reveal age-related and Alzheimer’s-related memory decline
Episodic memory - composed of memory for unique spatiotemporal experiences - is known to decline with aging, and even more severely in Alzheimer 's disease (AD). Memory for trial-unique objects in spatial scenes depends on the integrity of the hippocampus and interconnected structures that are among the first areas affected in AD. We reasoned that memory for objects-in-scenes would be impaired ...
متن کاملCan age-associated memory decline be treated?
Many older adults believe that their memory is not as good as it was when they were younger. An epidemiologic study in Finland documented that 76% of persons over the age of 60 years reported problems with their memory.1 Age-associated memory decline has been well studied and refers to changes in the aging brain that affect cognition but have no clear pathologic explanation. Because of the rapi...
