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.
LiveAmp is an ultra-lightweight, wearable amplifier. As it is wireless and allows you to store the data internally (exchangeable memory card), there are no mobility limitations. LiveAmp is easy and intuitive to use and extremely compact. Its technical specifications leave nothing to be desired and translate into outstanding signal quality.
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.
Compared to other senses, very little is known about taste. In a recent study (Crouzet, S. M., Busch, N. A., & Ohla, K. (2015). Taste quality decoding parallels taste sensations. Current Biology, 25(7), 890-896.), we used mulitvariate pattern analysis of single-trial EEG data to investigate which information about a taste is represented in taste-evoked brain responses.
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.
Vigilance (or brain arousal) strongly influences performance and neurophysiological reactions to stimuli and tasks. Dysregulation of vigilance is an important element in the pathophysiology of neuropsychiatric diseases. VIGALL 2.0 provides a tool to assess this basic aspect of brain function.
This user research summary is based on an article published as Rustamov, N., Rodriguez-Raecke, R., Timm, L., Agrawal, D., Dressler, D., Schrader, C., … Kopp, B. (in press). “Attention shifting in Parkinson’s disease: An analysis of behavioral and cortical responses”. Neuropsychology. which was designed to examine persistent (input selection) versus transient (input shifting) mechanisms of attention control in Parkinson’s disease (PD).
Currently there is a tendency to more and more use EEG not only for clinical analysis but also for Brain-Computer Interfaces (BCIs) for disabled people, for gaming, or for supervision, e.g, during driving. Here, it is important to know how many sensors are needed, and how they should be placed. This enables an easy setup of the electrode cap with reduced resources, while at the same time maintaining the system’s performance. The summarized article deals with this topic and introduces and compares several methods to choose relevant electrodes (sensors).
