EEG-fMRI Safety Updates: Protecting the BrainAmp MR family and PowerPack

We strive to provide detailed safety and setup guidelines for performing simultaneous EEG-fMRI. This article explains factors related to the gradient magnetic field, which influence heating in the amplifiers and batteries during functional imaging. We also provide updated guidelines on how to protect the BrainAmp MR and Power Pack.

How to decide which EEG amplifier best fits your research

You would like to start with EEG research, but you are unsure what amplifier works best for you? Given the range of possibilities, it can be hard to choose the best EEG amplifier for your research. If you could use some guidance, this article is a good start for you!

  • SyncBox Scanner Interface Duo

Coming soon: SyncBox Scanner Interface capable of receiving fiber optic inputs

Syncing BrainAmp MR’s sampling clock to the MR scanner’s clock is essential for achieving the best EEG-fMRI data quality. The SyncBox with its Scanner Interface ensures that this is done. We have extended the interface by an optical input so that our new SyncBox Scanner Interface Duo connects to both electrical and optical MR Scanner sync outputs.

  • EEG amplifier signal pipeline, and why you (mostly) do not need to worry about aliasing

EEG amplifier signal pipeline, and why you (mostly) do not need to worry about aliasing

An EEG signal goes through various transformations on both the hardware- and software-level before being saved on the hard disk or being displayed on the screen. This article explains the pipeline principles and highlights the difference between user-configurable filters vs. automatic filters that prevent aliasing artifacts by design.

  • 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.

  • 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.
