A hierarchical framework for cortical and subcortical gray-matter parcellation across rodents, primates, and humans

Nature Communications, Published online: 23 July 2026; doi:10.1038/s41467-026-75837-5 Researchers built a unified atlas that maps matching gray-matter regions across mouse, rat, marmoset, macaque, and human, enabling direct cross-species comparison and revealing conserved sensorimotor but divergent association-cortex organization.
