Human achievement at high altitude requires the performance of skilled behaviors with cognitive clarity. To better understand how the brain changes at high altitude during a motor task we used the actiCAP Xpress Bundle to characterize motor circuit changes up to 4,130 meters in the Himalayan mountains of Nepal.
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.
We would like to announce a change in the licensing structure of our analysis and recording Software BrainVision Analyzer and BrainVision Recorder. Overall, this change leads to a major reduction of prices for the initial purchase of a Brain Products Software product (BrainVision Analyzer and BrainVision Recorder) and increased simplicity for the ordering process.
In a recent study (Müller, B. C. N., Kühn-Popp, N., Meinhardt, J., Sodian, B., & Paulus, M. 2015. Long-term stability in children’s frontal EEG alpha asymmetry between 14-months and 83-months. International Journal of Developmental Neuroscience, 41, 110-114), we measured resting state alpha EEG in children at two measurement points. This user research article provides an overview of our study.
The most widely used EEG equipment for simultaneous EEG/BOLD fMRI acquisition consists of the BrainAmp MR plus, RecView and Analyzer 2. Thus, the Brain Products’ Technical Support team has great experience in helping our customers to solve technical problems concerning EEG/fMRI studies. In this article, we share our experience by presenting an overview of the most important set up steps for a successful EEG/fMRI experiment.
The 2.1.1 release of BrainVision Analyzer 2 will be out on December 18, 2015. The focus of this release was the integration of user feedback, improved usability and even more speed. In this article we will talk about some of the updates and give you the link to the full release notes.
Motor imagery (MI) combined with neurofeedback has been suggested as a promising rehabilitation approach for paralyzed individuals. EEG based MI feedback is particularly promising for therapeutic applications. Yet whether EEG feedback indeed targets specific sensorimotor activation patterns cannot unambiguously inferred from EEG alone. This article demonstrates that online correction of gradient artifacts and ballistocardiogram artifacts enables reliable MI EEG feedback inside the MRI scanner.
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.
Would you like to statically explore all time-points, all electrodes for all experimental conditions in less than one hour? BESA Statistics is an easy to use stand-alone application to calculate non-parametric permutation statistics for EEG, MEG and source imaging data. The newest version 2.0 released in July 2015 is directly compatible with the BrainVision native format which allows you to do all your data processing in BrainVision Analyzer 2 and then switch to BESA Statistics for statistical evaluation of your neurophysiological data.
Brain Products is a reliable partner when it comes to assuring timing accuracy between physical stimuli, markers and the EEG data stream. In the past months we were contacted by several BrainVision Analyzer 2 users that record with third party soft and hardware and asked how to correct offsets when it comes to marker timing.
