A metric survey on the sagittal and coronal morphology of the precuneus in adult humans.

The size, cortical surface area, length and height of the precuneus vary greatly in adult humans. The precuneus is also proportionally much larger in humans than in other primates, and its dorsal region is larger in our species compared with extinct hominids. Its longitudinal and vertical proportions can depend on a real cortical expansion, or on a deformation of the whole brain form due to cranial constraints.

Parietal Bone Thickness and Vascular Diameters in Adult Modern Humans: A Survey on Cranial Remains.

Cranial bone thickness varies among modern humans, and many factors influencing this variability remain unclear. Growth hormones and physical activity are thought to influence the vault thickness. Considering that both systemic factors and energy supply influence the vascular system, and taking into account the structural and biomechanical interaction between endocranial vessels and vault bones, in this study we evaluate the correlation between vascular and bone diameters.
