Principal components of functional connectivity: A new approach to study dynamic brain connectivity during rest
Functional connectivity (FC) as measured by correlation between fMRI BOLD time courses of distinct brain regions has revealed meaningful organization of spontaneous fluctuations in the resting brain. However, an increasing amount of evidence points to non-stationarity of FC; i.e., FC dynamically changes over time reflecting additional and rich information about brain organization, but represent...
متن کاملBrain Functional Connectivity Changes During Learning of Time Discrimination
The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...
متن کاملAtypical functional brain connectivity during rest in autism spectrum disorders.
OBJECTIVE Connectivity atypicalities in autism spectrum disorders (ASD) have been extensively proposed. The default mode network (DMN) is critical in this study, given the insight it provides for long-distance connectivity, and the importance of regions in this network for introspection and social emotion processing, areas affected in ASD. However, study of this network has largely been limited...
متن کاملEvaluation of Model-Based Methods in Estimating Dynamic Functional Connectivity of Brain Regions
Today, neuroscientists are interested in discovering human brain functions through brain networks. In this regard, the evaluation of dynamic changes in functional connectivity of the brain regions by using functional magnetic resonance imaging data has attracted their attention. In this paper, we focus on two model-based approaches, called the exponential weighted moving average model and the d...
متن کاملErratum to "On spurious and real fluctuations of dynamic functional connectivity during rest"
The authorswould like to correct an error in the derivation of the formula for sliding-window covariance of pure sinusoidal signals that are phaselocked (i.e., when fluctuations are spurious). While the derivation of the second term of Eq. (2) correctly uses the product-to-sum trigonometric identity, there is a missing factor of 2 in the similar derivation of the first term of Eq. (2); i.e., af...
