Journal ArticleDOI
Aging reduces neural specialization in ventral visual cortex
TL;DR: Whether neural structures become less functionally differentiated and specialized with age is investigated, and results demonstrated significantly less neural specialization for these stimulus categories in older adults across a range of analyses.
Journal ArticleDOI
Neural Specialization for Letter Recognition
Thad A. Polk,Matthew Stallcup,Geoffrey K. Aguirre,David C. Alsop,Mark D'Esposito,John A. Detre,Martha J. Farah +6 more
TL;DR: Results demonstrate that neural specialization in the human brain can extend to a category of stimuli that is culturally defined and that is acquired many years postnatally.
Journal ArticleDOI
A Functional Magnetic Resonance Imaging Study of Neural Dissociations between Brand and Person Judgments
TL;DR: Comparisons of neural correlates of product versus human descriptor judgments indicated greater activation in the medial prefrontal cortex regions for persons; for products, activation was greater in the left inferior prefrontal cortex, an area known to be involved in object processing.
Journal Article
Cerebral aging: integration of brain and behavioral models of cognitive function.
TL;DR: Both behavioral and neuroscience perspectives on cognitive aging are reviewed, and the findings in the two areas are connected to suggest important unresolved questions and directions for future research.
