"If at all possible, we need to keep fetuses in utero to protect them from the hazards that can occur in the extra uterine environment," she said in a hospital system news release.

The researchers said that during the third trimester of pregnancy, the fetal brain grows exponentially. The brain increases fourfold in size during this time, the researchers added.

The study included 75 preterm infants born before 32 weeks of pregnancy. The mean gestational age was 27 weeks. These babies weighed less than 1,500 grams (3.3 pounds) at birth. They showed no signs of structural brain injury.

The preterm babies were compared to 130 infants born full term at a mean age of 39 weeks of pregnancy. The mean birth weight was nearly 3,400 grams (almost 7.5 pounds), the study authors said.

A comparison of the infants' brains in the third trimester (the final 13 to 14 weeks of pregnancy) revealed that the premature infants had lower volumes in the cerebrum, cerebellum, brain stem intracranial cavity.

The cerebrum is the largest part of the brain controls speech, thoughts, emotions, learning muscle function. The cerebellum is involved in learning, social-behavioral functions complex motor functions, also controls the balance needed to stup walk. The brain stem carries information between the brain, the cerebellum the spinal cord, the study authors explained.

"What is really unique about these study results is for the very first time we have an opportunity to better understthe ways in which we care for preemies throughout their hospitalization that optimize brain development place more emphasis on those activities," Limperopoulos said.

The study was published Oct. 28 in the journal Pediatrics.
