Erratum 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...
متن کاملOn spurious and real fluctuations of dynamic functional connectivity during rest
Functional brain networks reconfigure spontaneously during rest. Such network dynamics can be studied by dynamic functional connectivity (dynFC); i.e., sliding-window correlations between regional brain activity. Key parameters-such as window length and cut-off frequencies for filtering-are not yet systematically studied. In this letter we provide the fundamental theory from signal processing t...
متن کاملPrincipal 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 کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولAtypical 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...
