Newborn gestational age (GA) and birth indicators (birth weight, birth length and head circumference) have been used as clinical indicators to assess the level of brain development. Cerebral changes are particularly intense during the last weeks of gestation. Previous studies have shown that the total brain volume at birth is about one third of the brain volume of healthy adults[1], but it remains unclear about the effect factors of brain volume. Our studies have shown that compared with other birth indicators, the gestational age of full-term newborns is strongly correlated with brain volume.
