| Popis: | Structural and functional changes of the brain have been reported in premature babies. To evaluate the relationship of functional and structural connectivity with gestational age, body growth and brain maturation in very preterm babies. We studied 18 very preterm babies (gestational age: mean ± standard deviation, 29.7±1.7 weeks). We examined functional connectivity by multivariate pattern analysis of resting-state functional MRI data. We assessed structural connectivity by analysis of diffusion tensor imaging data and probabilistic tractography. The average functional connectivity of the medial orbitofrontal cortex with the rest of the brain was positively associated with gestational age (P |
