Predicting human resting-state functional connectivity from structural connectivity.
In the cerebral cortex, the activity levels of neuronal populations are continuously fluctuating. When neuronal activity, as measured using functional MRI (fMRI), is temporally coherent across 2 populations, those populations are said to be functionally connected. Functional connectivity has previously been shown to correlate with structural (anatomical) connectivity patterns at an aggregate le...
متن کاملPrediction of functional connectivity from structural brain connectivity
Introduction: Studies that examine the relationship of functional and structural connectivity are important in interpreting neurophysiological data. Although, the relationship between functional and structural connectivity has been explored with a number of statistical tools [1, 2], there is no explicit attempt to quantitatively measure how well functional data can be predicted from structural ...

متن کاملDevelopment of structural and functional connectivity
Synopsis In the human brain, development of structural connectivity starts during the early fetal period, and progresses in a complex but sequential way, until all major axonal pathways become established in the preterm period, as outlined by post mortem and in vivo studies based on histological stainings and MRI. Through the myelination process, these networks further mature and refine after t...
متن کاملResting State Functional Connectivity in Perfusion Imaging: Correlation Maps with BOLD Connectivity and Resting State Perfusion
Functional connectivity is a property of the resting state that may provide biomarkers of brain function and individual differences. Classically, connectivity is estimated as the temporal correlation of spontaneous fluctuations of BOLD signal. We investigated differences in connectivity estimated from the BOLD and CBF signal present in volumes acquired with arterial spin labeling technique in a...
