Head circumference as an index of brain weight in the fetus and newborn.
Postmortem brain weight and head circumference were measured in 485 fetuses and newborn infants. A cubic relationship was demonstrated between these two variables in normal infants. Statistically, a significantly larger brain weight for a given head circumference was found in small-for-gestational-age infants.
