Predictors of real-time fMRI neurofeedback performance and improvement-A machine learning mega-analysis
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Yury Koush, Kirsten Emmert
Real-time fMRI neurofeedback is an increasingly popular neuroimaging technique that allows an individual to gain control over his/her own brain signals, which can lead to improvements in behavior in healthy participants as well as to improvements of clinic ...
2021The role of the subgenual anterior cingulate cortex in dorsomedial prefrontal-amygdala neural circuitry during positive-social emotion regulation
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Yury Koush, Gwladys Rey
Positive-social emotions mediate one's cognitive performance, mood, well-being, and social bonds, and represent a critical variable within therapeutic settings. It has been shown that the upregulation of positive emotions in social situations is associated ...
2020Can we predict real-timefMRIneurofeedback learning success from pretraining brain activity?
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Kirsten Emmert, Maria Laura Blefari
Neurofeedback training has been shown to influence behavior in healthy participants as well as to alleviate clinical symptoms in neurological, psychosomatic, and psychiatric patient populations. However, many real-time fMRI neurofeedback studies report lar ...
2020Data-driven tensor independent component analysis for model-based connectivity neurofeedback
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Yury Koush, Nemanja Masala
Neurofeedback based on real-time functional MRI is an emerging technique to train voluntary control over brain activity in healthy and disease states. Recent developments even allow for training of brain networks using connectivity feedback based on dynami ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2019Building perception block by block: a response to Fekete et al.
Michael Herzog, Frank Scharnowski, Adrien Christophe Doerig
Is consciousness a continuous stream, or do percepts occur only at certain moments of time? This age-old question is still under debate. Both positions face difficult problems, which we proposed to overcome with a 2-stage model, where unconscious processin ...
Oxford University Press (OUP)2019No 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 ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2019Brain networks for engaging oneself in positive-social emotion regulation
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Yury Koush
Positive emotions facilitate cognitive performance, and their absence is associated with burdening psychiatric disorders. However, the brain networks regulating positive emotions are not well understood, especially with regard to engaging oneself in positi ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2019Using real-time fMRI neurofeedback to restore right occipital cortex activity in patients with left visuo-spatial neglect: proof-of-principle and preliminary results
Dimitri Nestor Alice Van De Ville, Frank Scharnowski
Hemineglect is common after right parietal stroke, characterised by impaired awareness for stimuli in left visual space, with suppressed neural activity in the right visual cortex due to losses in top-down attention signals. Here we sought to assess whethe ...
ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD2019Learning Control Over Emotion Networks Through Connectivity-Based Neurofeedback
Dimitri Nestor Alice Van De Ville, Djalel Eddine Meskaldji, Frank Scharnowski, Yury Koush, Gwladys Rey
Most mental functions are associated with dynamic interactions within functional brain networks. Thus, training individuals to alter functional brain networks might provide novel and powerful means to improve cognitive performance and emotions. Using a nov ...
Oxford University Press2017Distributed Patterns of Brain Activity Underlying Real-Time fMRI Neurofeedback Training
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Kirsten Emmert, Rotem Roza Kopel
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 ...
