The relationship between age, neural differentiation, and memory performance
JD Koen, N Hauck, MD Rugg - Journal of Neuroscience, 2019 - Soc Neuroscience
Healthy aging is associated with decreased neural selectivity (dedifferentiation) in category-
selective cortical regions. This finding has prompted the suggestion that dedifferentiation …

Dedifferentiation in the visual cortex: an fMRI investigation of individual differences in older adults
Dedifferentiation, or decreased processing specificity, has been suggested to represent a
ubiquitous characteristic of cognitive aging. In this study, we examined both age-related …

Age-related neural dedifferentiation and cognition
This review focuses on possible contributions of neural dedifferentiation to age-related
cognitive decline. Neural dedifferentiation is held to reflect a breakdown in the functional …

Pattern separation deficits associated with increased hippocampal CA3 and dentate gyrus activity in nondemented older adults
There is widespread evidence that memory deteriorates with aging, however the exact
mechanisms that underlie these changes are not well understood. Given the growing size of …

Age differences in neural distinctiveness revealed by multi-voxel pattern analysis
Current theories of cognitive aging argue that neural representations become less distinctive
in old age, a phenomenon known as dedifferentiation. The present study used multi-voxel …

Age-related individual variability in memory performance is associated with amygdala-hippocampal circuit function and emotional pattern separation
While aging is generally associated with episodic memory decline, not all older adults
exhibit memory loss. Furthermore, emotional memories are not subject to the same extent of …

[HTML][HTML] Age differentiation within gray matter, white matter, and between memory and white matter in an adult life span cohort
It is well established that brain structures and cognitive functions change across the life
span. A long-standing hypothesis called “age differentiation” additionally posits that the …
