Outline of Final Research Achievements

After birth, brain image and mental development of premature infants who were admitted to the maternity maternal center were examined. We measured 3D-MRI of 48 extremely low birth weight infants at the time of maturity and measured intracranial volume and total cerebral volume of the brain, and it was found that head circumference has a strong positive correlation with cerebral volume. The Bayley infant development test which is internationally widely used was carried out at the age of 1 year and 3 years old. As a result, it was suggested that developmental stages differed in each function, and development of coarse exercise, especially in the language domain and the motor domain, was characteristic during the period of 1 year and a half to 3 years.
