Neural dedifferentiation in the aging brain

JD Koen, MD Rugg - Trends in cognitive sciences, 2019 - cell.com
Many cognitive abilities decline with age even in the absence of detectable pathology.
Recent evidence indicates that age-related neural dedifferentiation, operationalized in terms …

Age-related neural dedifferentiation and cognition

JD Koen, S Srokova, MD Rugg - Current Opinion in Behavioral Sciences, 2020 - Elsevier
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 …

Cerebral aging: integration of brain and behavioral models of cognitive function

DC Park, TA Polk, JA Mikels, SF Taylor… - Dialogues in clinical …, 2001 - Taylor & Francis

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 …

[HTML][HTML] Functional dedifferentiation and altered connectivity in older adults: neural accounts of cognitive aging

JOS Goh - Aging and disease, 2011 - ncbi.nlm.nih.gov
Aging is associated with myriad changes in behavioral performance and brain structure and
function. Given this complex interplay of brain and behavior, two streams of findings are …

[HTML][HTML] Age differentiation within gray matter, white matter, and between memory and white matter in an adult life span cohort

SMM de Mooij, RNA Henson, LJ Waldorp… - Journal of …, 2018 - Soc Neuroscience
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 …

Structure–function correlates of cognitive decline in aging

J Persson, L Nyberg, J Lind, A Larsson… - Cerebral …, 2006 - academic.oup.com
To explore neural correlates of cognitive decline in aging, we used longitudinal behavioral

Individual differences in the cognitive and neurobiological consequences of normal aging

PR Rapp, DG Amaral - Trends in neurosciences, 1992 - cell.com
Defining the neural basis of age-related cognitive dysfunction is a major goal of current
research on aging. Compelling evidence from laboratory animals and humans indicates that …
