abstract = {Differences in brain size between the sexes are
consistently reported. However, the consequences of this
anatomical difference on sex differences in intrinsic brain
function remain unclear. In the current study, we
investigate whether sex differences in intrinsic cortical
functional organization may be associated with differences
in cortical morphometry, namely different measures of brain
size, microstructure, and the geodesic distance of
connectivity profiles. For this, we compute a low
dimensional representation of functional cortical
organization, the sensory-association axis, and identify
widespread sex differences. Contrary to our expectations,
sex differences in functional organization do not appear to
be systematically associated with differences in total
surface area, microstructural organization, or geodesic
distance, despite these morphometric properties being per se
associated with functional organization and differing
between sexes. Instead, functional sex differences in the
sensory-association axis are associated with differences in
functional connectivity profiles and network topology.
Collectively, our findings suggest that sex differences in
functional cortical organization extend beyond sex
differences in cortical morphometry.},
