abstract = {The human cerebral cortex is symmetrically organized along
large-scale axes but also presents inter-hemispheric
differences in structure and function. The quantified
contralateral homologous difference, i.e., asymmetry, is a
key feature of the human brain left-right axis supporting
functional processes, such as language. Here, we assessed
whether the asymmetry of cortical functional organization is
heritable and phylogenetically conserved between humans and
macaques. Our findings indicate asymmetric organization
along an axis describing a hierarchical functional
trajectory from perceptual/action to abstract cognition.
Whereas language network showed leftward asymmetric
organization, frontoparietal network showed rightward
asymmetric organization. These asymmetries were heritable
and comparable between humans and macaques, suggesting
(phylo)genetic conservation. However, both language and
frontoparietal networks showed a qualitatively larger
asymmetry in humans relative to macaques and variable
heritability in humans. This may reflect an evolutionary
adaptation allowing for experience-dependent specialization,
linked to higher-order cognitive functions uniquely
developed in humans.},
