abstract = {Determining the brain specializations unique to humans
requires directly comparative anatomical information from
other primates, especially our closest relatives. Human
(Homo sapiens) (m/f), chimpanzee (Pan troglodytes) (f), and
rhesus macaque (Macaca mulatta) (m/f) white matter atlases
were used to create connectivity blueprints, i.e.,
descriptions of the cortical grey matter in terms of the
connectivity with homologous white matter tracts. This
allowed a quantitative comparative of cortical organization
across the species. We identified human-unique connectivity
profiles concentrated in temporal and parietal cortices, and
hominid-unique organization in prefrontal cortex. Functional
decoding revealed human-unique hotspots correlated with
language processing and social cognition. Overall, our
results counter models that assign primacy to prefrontal
cortex for human uniqueness.Significance statement
Understanding what makes the human brain unique requires
direct comparisons with other primates, particularly our
closest relatives. Using connectivity blueprints, we
compared to cortical organization of the human to that of
the macaque and, for the first time, the chimpanzee. This
approach revealed human-specific connectivity patterns in
the temporal and parietal lobes, regions linked to language
and social cognition. These findings challenge traditional
views that prioritize the prefrontal cortex in defining
human cognitive uniqueness, emphasizing instead the
importance of temporal and parietal cortical evolution in
shaping our species' abilities.},
