Understanding how sleep affects the human thalamus with EEG-fMRI

We are able to show using EEG-fMRI that the functional connectivity of the thalamus is generally increased by sleep onset and depth, and that sleep has a differential effect on sub-divisions of the thalamus. EEG-fMRI is a vital tool to understand the impact of sleep on cortical and subcortical processing.

New views made easy – Visualizing ECoG grids & connectivity matrices via Analyzer 2’s MATLAB® transformation

BrainVision Analyzer 2 is easy to use and offers a variety of views to display your data with a single mouse click. However, science develops and new analysis methods entail the need for new data visualizations that Analyzer 2 does not yet support. This article briefly discusses how to expand the view capabilities of Analyzer 2 using the MATLAB® transformation. Two examples will illustrate this feature, where ECoG grid data and EEG connectivity matrices are visualized using simple MATLAB® functions.

  • EEG-assisted retrospective motion correction for fMRI (E-REMCOR) and automated implementation (aE-REMCOR)

EEG-assisted retrospective motion correction for fMRI (E-REMCOR) and automated implementation (aE-REMCOR)

Electroencephalography (EEG) concurrently acquired with fMRI provides high temporal resolution information about brain activity as well as subject head movement. We introduced an EEG-assisted retrospective motion correction (E-REMCOR) method that utilizes EEG data to correct for head movements in fMRI on a slice-by-slice basis and substantially improves the quality of the data. To further enhance the usability of E-REMCOR, especially for the large-scale EEG-fMRI studies, we developed an automatic and improved implementation of E-REMCOR, referred as aE-REMCOR.

Men at work: Mobile EEG as a new tool for neuroergonomics

Our recent study “Age-sensitive effects of enduring work with alternating cognitive and physical load. A study applying mobile EEG in a real life working scenario” demonstrates how mobile EEG can be utilized not only for user state examination but also for the evaluation of cognitive processing in real life working situations. Here is a summary of our publication.

  • All you ever wanted to know about markers in BrainVision Analyzer 2

All you ever wanted to know about markers in BrainVision Analyzer 2

Why markers? Investigating electrophysiological effects that evolve over hundreds of milliseconds requires precisely timed triggers that can be used for trial alignment or averaging. This article will give you an overview of how to manage, edit and process your markers most efficiently in Analyzer 2.

Recording brain waves in extreme situations: The psychoactivity of ayahuasca

This user research summary is based on the article “Acute Biphasic Effects of Ayahuasca“. Ayahuasca is an amerindian psychoactive sacrament used worldwide. Neuroscience studies have shown contradictory results regarding its effects in the brain. Combining EEG, plasma samples and robust statistics, we’ve uncovered biphasic effects in the brain which are related to many psychoactive compounds, not only N,N-dimethyltryptamine (DMT), as previously proposed.

Exports for all occasions – A selective overview of Analyzer 2’s most useful export options

BrainVision Analyzer 2 offers some nice export options that will suit (almost) every need for external processing. This article will summarize the most important routes out of Analyzer 2 and give some examples of how to use them within your own analysis.

Vibration induced EEG artifacts during simultaneous EEG-fMRI

The most prominent MR-related EEG artifacts are gradient artifacts and the ballistocardiogram. However, vibrations represent another problematic source of artifacts. Therefore, noise assessment and reduction is of special importance for EEG measurements within the MR scanner.
