Weak functional connectivity in the human fetal brain prior to preterm birth
It has been suggested that neurological problems more frequent in those born preterm are expressed prior to birth, but owing to technical limitations, this has been difficult to test in humans. We applied novel fetal resting-state functional MRI to measure brain function in 32 human fetuses in utero and found that systems-level neural functional connectivity was diminished in fetuses that would...
متن کاملFunctional connectivity hubs in the human brain
Brain networks appear to have few and well localized regions with high functional connectivity density (hubs) for fast integration of neural processing, and their dysfunction could contribute to neuropsychiatric diseases. However the variability in the distribution of these brain hubs is unknown due in part to the overwhelming computational demands associated to their localization. Recently we ...
متن کاملHubs in the human fetal brain network
Advances in neuroimaging and network analyses have lead to discovery of highly connected regions, or hubs, in the connectional architecture of the human brain. Whether these hubs emerge in utero, has yet to be examined. The current study addresses this question and aims to determine the location of neural hubs in human fetuses. Fetal resting-state fMRI data (N = 105) was used to construct conne...
متن کاملFunctional Connectivity of the Infant Human Brain
Infancy is a critical and immensely important period in human brain development. Subtle changes during this stage may be greatly amplified with the unfolding of different developmental processes, exerting far-reaching consequences. Studies of the structure and behavioral manifestations of the infant brain are fruitful. However, the specific functional brain mechanisms that enable the execution ...
متن کاملDeveloping Connectivity in Human Fetal Brains: Emerging Regional Variations
18W and 20W: Dominant radial pathways from the ventricular margin to the brain surface were found across most of the brain areas (Fig.1 left). At these stages, the radial pathways contain radial glial pathways, migrating neurons, and axons from those neurons [Rakic 2009]. We also observed intracortical horizontal short pathways that may reflect forming horizontal interneuron connections. Projec...
