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.
In this article we present a collection of common EEG artifacts with their characteristics and pictures to facilitate their identification, and various tools offered by BrainVision Analyzer 2 for artifact detection, rejection, and removal. Towards the end we make some suggestions for devising an overall artifact handling strategy.
Many of you might already be using the Wireless Trigger system to facilitate experiments that are utilizing the LiveAmp’s potential as a mobile amplifier. By pairing a single transmitter with multiple receivers, you can now maximize the possibilities of such a mobile experiment by adding more LiveAmps to run hyperscanning experiments.
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!

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.
In this article we will dip into common analysis goals for hyperscanning and why they are relevant for research fields such as social neuroscience. We will focus on dealing with multi-participant datasets and inter-brain connectivity in BrainVision Analyzer 2 helping you to complete your hyperscanning analysis.
After E-Prime, Presentation, and Experiment Builder, we now introduce the integration of code in PsychoPy that allows you to remotely control BrainVision Recorder directly from the Python-based open source stimulus presentation software.
In this part of our peripheral physiology series we introduce ECG measurement using BrainAmp ExG MR in the MR environment. The safety issues associated with ECG in the MR environment are highlighted. We explain the mechanisms which may limit the signal quality and introduce a methodology to obtain precise heart rate information.
In this hyperscanning series, we first introduced our gold standard solution based on BrainAmps, then a wireless solution using CGX Quick headsets and the StimTrigger, as well as the extremely flexible LSL solution. In this fourth part, we demonstrate another hardware-based option: using the trigger mirror mode which can be used with actiCHamp Plus and LiveAmp together with the Sensor & Trigger Extension.
