No time for drifting: Comparing performance and applicability of signal detrending algorithms for real-time fMRI

Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Yury Koush, Rotem Roza Kopel

As a consequence of recent technological advances in the field of functional magnetic resonance imaging (fMRI), results can now be made available in real-time. This allows for novel applications such as online quality assurance of the acquisition, intra-op ...

Distributed Patterns of Brain Activity Underlying Real-Time fMRI Neurofeedback Training

Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Rotem Roza Kopel, Kirsten Emmert

Neurofeedback (NF) based on real-time functional magnetic resonance imaging (rt-fMRI) is an exciting neuroimaging application. In most rt-fMRI NF studies, the activity level of a single region of interest (ROI) is provided as a feedback signal and the part ...

Neurofeedback Using Real-Time fMRI : Impact on Functional Network Organization

Rotem Roza Kopel

Over the last decade, technological advances in the field of functional magnetic resonance imaging (fMRI) have made it possible to obtain localized measures of brain activity in real-time. This allows for applications such as online quality control of the ...

Meta-analysis of real-time fMRI neurofeedback studies using individual participant data: How is brain regulation mediated?

Dimitri Nestor Alice Van De Ville, Rotem Roza Kopel, Kirsten Emmert

An increasing number of studies using real-time fMRI neurofeedback have demonstrated that successful regulation of neural activity is possible in various brain regions. Since these studies focused on the regulated region(s), little is known about the targe ...

Dynamic reconfiguration of human brain functional networks through neurofeedback

Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Rotem Roza Kopel

Recent fMRI studies demonstrated that functional connectivity is altered following cognitive tasks (e.g., learning) or due to various neurological disorders. We tested whether real-time fMRI-based neurofeedback can be a tool to voluntarily reconfigure brai ...

Recovery of the default mode network after demanding neurofeedback training occurs in spatio-temporally segregated subnetworks

Dimitri Nestor Alice Van De Ville, Rotem Roza Kopel

The default mode (DM) network is a major large-scale cerebral network that can be identified with functional magnetic resonance imaging (fMRI) during resting state. Most studies consider functional connectivity networks as stationary phenomena. Consequentl ...
