The cranial vault is the space in the skull within the neurocranium. The brain is found in the cranial vault, and brain size may be affected by the size of the vault as shown in craniometry, but studies relating it to intelligence have been ambivalent.
Cranial vault size is directly proportional to skull size and is developed early.[1]
- ^ "Changes in vault dimensions must occur by early childhood because of the early development of the vault." Secular change in craniofacial morphology "During the 125 years under consideration, cranial vaults have become markedly higher, somewhat narrower, with narrower faces. The changes in cranial morphology are probably in large part due to changes in growth at the cranial base due to improved environmental conditions. The changes are likely a combination of phenotypic plasticity and genetic changes over this period." Cranial change in Americans: 1850-1975.
