Overview
Comparative neuroanatomical review maps discrete bilateral hubs of the default mode network across mammalian species, highlighting an evolutionarily conserved architecture for cognitive processing.
Key Points
- Characterize the anatomical structure, distribution, and evolutionary conservation of the default mode network and attention-related cortical networks across species.
- Comparative anatomical mapping across humans, nonhuman primates, cats, and rodents.
- Structural localization within medial and lateral parietal, medial prefrontal, and temporal cortices.
- Identified discrete, bilateral, and symmetrical cortical regions that form the core default mode network across diverse mammalian brains.
- Demonstrated consistent spatial distribution across medial parietal, medial prefrontal, and temporal cortical hubs across mammalian taxa.
