Automatic and robust noise suppression in EEG and MEG: The SOUND algorithm

Tuomas P. Mutanen, Johanna Metsomaa, Sara Liljander, Risto J. Ilmoniemi
2018 NeuroImage  
A B S T R A C T Electroencephalography (EEG) and magnetoencephalography (MEG) often suffer from noise-and artifactcontaminated channels and trials.  ...  As a result, we are able to identify and suppress noise and artifacts in EEG and MEG.  ...  In addition, we would like to thank Prof. Sarvas for providing tools for the MATLAB demo package.  ...

EEG and TMS-EEG Studies on the Cortical Excitability and Plasticity associated with Human Motor Control and Learning

Myriam Taga
The first study used TMS-EEG to examine differences in cortical excitability related to motor dominance by applying TMS over the dominant and non-dominant M1 at rest and during contraction.  ...  To this end electroencephalography (EEG), transcranial magnetic stimulation (TMS), simultaneous TMS-EEG were employed during a simple motor and a highly standardised robot-mediated task.  ...  TMS-EEG Collectively, the studies have shown that TMS-EEG is a useful tool to study cortical excitability providing reliable and reproducible readouts by measuring direct cortical responses to TMS with  ...

Concurrent TMS-fMRI for causal network perturbation and proof of target engagement

Til Ole Bergmann, Rathiga Varatheeswaran, Colleen A Hanlon, Kristoffer H Madsen, Axel Thielscher, Hartwig Roman Siebner
2021 NeuroImage  
We will also discuss how concurrent TMS-fMRI during a behavioral task can help to link behavioral TMS effects to changes in neural network activity and to identify peripheral co-stimulation confounds.  ...  We will introduce the technical challenges and state-of-the art solutions and provide a comprehensive overview of the existing literature and the available experimental approaches.  ...  Siebner holds a 5-year professorship in precision medicine at the Faculty of Health Sciences and Medicine, University of Copenhagen which is sponsored by the Lundbeck Foundation (Grant Nr.  ...

Current State and Future Prospects of EEG and fNIRS in Robot-Assisted Gait Rehabilitation: A Brief Review

Alisa Berger, Fabian Horst, Sophia Müller, Fabian Steinberg, Michael Doppelmayr
2019 Frontiers in Human Neuroscience  
While previous studies have examined either EEG or fNIRS with respect to RAGT, a multi-modal integration of both approaches is lacking.  ...  In this brief review, we surveyed neuroimaging studies focusing specifically on robotic gait rehabilitation.  ...  Recently, wearable and wireless systems were developed which allow the topographical representation of hemodynamic responses over the cortical surface due to high-density multi-distance channels (Shin  ...

Examining the Role and Neurophysiological Mechanisms of Social Support in Pain Experience

Xianwei Che
Social support plays a role in pain experience, however, this effect is context-dependent.  ...  The findings presented here suggest that social support generally has a protective effect on pain, particularly when it is clearly expressed by a significant other.  ...  TMS-EEG Data Analysis TMS-EEG data were preprocessed as previously described .  ...
