(2) Several semantic regions - including ATL and TPC - showed a task-dependent response to taxonomic and thematic relationships. Semantic control regions (e.g. left IFG, mPFC) flexibly responded to task-relevant semantic relations.
(3) Aging was associated with a decline in domain-general and domain-specific executive control, more right-hemispheric ATL involvement, and a shift from taxonomic towards thematic processing. Increased thematic activity was associated with higher accuracy but slower responses.
Three key findings emerged:
(1) Contrary to the dual-hub theory, ATL and TPC were sensitive to both taxonomic and thematic relationships, with a graded thematic bias.
🚨 I'm thrilled to share our new preprint on the representation of taxonomic and thematic semantic relationships in the human brain as a function of task demands and healthy aging: www.researchgate.net/publication/...
