Semantic and Phonological Brain Networks in Older Adults: A Systematic Scoping Review
In our scoping review of older adults, we found similarities with regions implicated in semantic and phonological processing in younger adults.
Regions with the potential for semantic and phonological specialization in older adults were largely confined to the ventral and dorsal stream pathways, respectively.
The results of this scoping review are generally compatible with the CRUNCH or de-differentiation hypothesis.
Complementary activation- and lesion-based meta-analyses in older adults are recommended.
