Exploring Dynamic Brain Functional Networks Using Continuous “State-Related” Functional MRI
We applied a "temporal decomposition" method, which decomposed a single brain functional network into several "modes"; each of them dominated a short temporal period, on a continuous, "state-" related, "finger-force feedback" functional magnetic resonance imaging experiment. With the hypothesis that attention and internal/external information processing interaction could be manipulated by diffe...
متن کاملExploring large-scale brain networks in functional MRI.
Increasing emphasis has been recently put on large-scale network processing of brain functions. To explore these networks, many approaches have been proposed in functional magnetic resonance imaging (fMRI). Their objective is to answer the following two questions: (1) what brain regions are involved in the functional process under investigation? and (2) how do these regions interact? We review ...
متن کاملStructural and Functional Brain Remodeling during Pregnancy with Diffusion Tensor MRI and Resting-State Functional MRI
Although pregnancy-induced hormonal changes have been shown to alter the brain at the neuronal level, the exact effects of pregnancy on brain at the tissue level remain unclear. In this study, diffusion tensor imaging (DTI) and resting-state functional MRI (rsfMRI) were employed to investigate and document the effects of pregnancy on the structure and function of the brain tissues. Fifteen Spra...
متن کاملMeasurement of dynamic task related functional networks using MEG
The characterisation of dynamic electrophysiological brain networks, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method for measuring such networks in the human brain using magnetoencephalography (MEG). Previous network analyses look for brain regions that share a common temporal profile of acti...
متن کاملDynamic Model of Functional Brain Networks
Functional brain networks are networks created with a help of fMRI measurements of the in vivo brain activity [3], [4]. I elaborated a dataset, which contains functional brain networks of young participants, healthy elderly participants and elderly participants with diagnosed Alzheimer disease. All networks were measured at the three different correlation thresholds. In this paper I present a d...
