Characterization of the Functional and Structural Development of the Human Neonatal Brain From 30 Wks to 45 Wks ga

Completed

Conditions studied: Human Development

In brief

The major goal of this project is to characterize the structural and functional development of cortical plate and white matter of the human neonatal brain from the equivalent 30 gestational weeks to 45 gestational weeks. The project is sponsored by niH R01MH092535. Furthermore, it is related to the blue print project of transcriptome atlas (niH RC2MH089921) with at least 36 million funding also sponsored by niH. Revealing detailed anatomy at different equivalent gestational ages of human neonatal brain not only aids in understanding this highly ordered process, but also provides clues to detect abnormalities caused by genetic or environmental factors. Cerebral vascular measurements offer important information on cerebral metabolism. However, either anatomical or functional studies of human brain development during this period are surprisingly scarce. Diffusion tensor imaging (DTi), a recently developed technology of magnetic resonance imaging (MRi), is capable of noninvasively delineating macroscopic anatomical components with high contrast and revealing structures at the microscopic level. Cerebral vascular quantification including cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRo2) can also be obtained through noninvasive MRi, specifically arterial spin labeling (aSL) and T2-relaxation under spin tagging (TRuST) MRi. in this proposed study, the structure and function of neonatal brain will be explored using noninvasive MRi technologies. 102 infants will be recruited and no sedation will be applied during MRi. The resultant database will provide reference standards for diagnostic radiology of premature newborns and reveal the vascular activities of these newborn brains. Specifically, three aims will be achieved: 1. To delineate the anatomical development of complex structure in the cerebral wall and white matter tracts of neonatal brains at different equivalent gestational ages. 2. To quantify the cerebral blood flow and metabolic rate of oxygen of neonatal brain. 3. To correlate the structural and functional measurements with the gene transcriptome results.
