abstract = {The hippocampus is a uniquely infolded allocortical
structure in the medial temporal lobe that consists of the
microstructurally and functionally distinct subregions:
subiculum, cornu ammonis, and dentate gyrus. The hippocampus
is a remarkably plastic region that is implicated in
learning and memory. At the same time it has been shown that
hippocampal subregion volumes are heritable, and that
genetic expression varies along a posterior to anterior
axis. Here, we studied how a heritable, stable, hippocampal
organisation may support its flexible function in healthy
adults. Leveraging the twin set-up of the Human Connectome
Project with multimodal neuroimaging, we observed that the
functional connectivity between hippocampus and cortex was
heritable and that microstructure of the hippocampus
genetically correlated with cortical microstructure.
Moreover, both functional and microstructural organisation
could be consistently captured by anterior-to-posterior and
medial-to-lateral axes across individuals. However,
heritability of functional, relative to microstructural,
organisation was found reduced, suggesting individual
variation in functional organisation may be explained by
experience-driven factors. Last, we demonstrate that
structure and function couple along an inherited macroscale
organisation, suggesting an interplay of stability and
plasticity within the hippocampus. Our study provides new
insights on the heritability of the hippocampal of the
structure and function within the hippocampal organisation.},
