Postnatal age-related change of brain volume and its association with neurobehavior outcome in term neonates

Neonatal period is an important stage of brain development, exploring the development and evolution of brain region at this stage is significant for studying brain development and disease mechanisms. We analyzed the relationship between segmented brain region volume and postnatal age in term neonates, the results showed that, after controlling for gestational age, birth weight, body length, head circumference and gender factors, the volume of most brain regions of neonates was positively correlated with postnatal age. In addition, there is no correlation between the volume of most brain regions and neurobehavioral scores.
