  • Safety and data quality of EEG recorded simultaneously with multi-band fMRI

Safety and data quality of EEG recorded simultaneously with multi-band fMRI

Until recently, there has been little information about EEG data quality and safety when used with newer multi-band (MB) fMRI sequences. Here, we measure the relative heating of a MB protocol compared with a standard single-band (SB) protocol considered to be safe. We also evaluated EEG quality recorded concurrently with the MB protocol on humans.

  • TurboLink – new solution enabling ultra-fast brain state-dependent research

TurboLink – new solution enabling ultra-fast brain state-dependent research

More and more applications require a setup which allows, data access within minimal time, but maximal reliability. We recently released TurboLink for actiCHamp (Plus) and partnered up with sync2brain and their bossdevice RESEARCH to offer a solution that makes sure you can always rely on the performance of your hardware setup.

  • How to do hyperscanning with LabStreamingLayer (LSL)

Hyperscanning series part 3: How to do hyperscanning with LabStreamingLayer (LSL)

So far, this series covered hyperscanning with BrainAmp amplifiers as well as with CGX Quick headsets. Part 3 introduces a more general approach, which is based on LabStreamingLayer (LSL).

  • Transcranial Evoked Potentials can be reliably recorded with active electrodes (Fig. 1)

Transcranial Evoked Potentials can be reliably recorded with active electrodes

In this article, based on our current work, we compared transcranial evoked potentials recorded with active and passive electrodes. Signals obtained with the two methods did not statistically differ in amplitude and topography, and showed a high degree of similarity across the scalp. We conclude that active electrodes are a viable solution for studies combining transcranial magnetic stimulation and electroencephalography.

  • The sound of silence: an EEG hyperscanning study

The sound of silence: an EEG study of how musicians time pauses in individual and joint music performance

We recently investigated how musical partners resolve unmeasured expressive silences in musical interaction. Partners resolved shorter silences more synchronously than longer silences; partners also displayed enhanced neural markers of motor preparation for shorter relative to longer silences. Thus, shorter silences in interaction may facilitate interpersonal coordination.

  • Carbon Wire Loops (CWLs) in EEG-fMRI studies of interictal epileptic activity

Carbon Wire Loops in EEG-fMRI studies of interictal epileptic activity

At the Montreal Neurological Institute and Hospital, we work with combined EEG and fMRI acquisition to study epileptic patients to determine the brain region responsible for the generation of seizures that characterize this condition. We use Carbon Wire Loops to help recover a clean signal from the EEG recorded in the MR environment.

  • First Steps to Using Carbon Wire Loops (CWLs) to Correct for Artifacts in simultaneous EEG-fMRI

First Steps to Using Carbon Wire Loops to Correct for Artifacts in simultaneous EEG-fMRI

EEG signals acquired in parallel to fMRI data require the handling of artifacts in the EEG dataset due to electrode motion, for example, by blood pulsation. Using carbon wire loops placed on EEG caps allows you to directly measure these artifacts and subsequently correct for them efficiently using a regression-based approach.
