Here we introduce a step-by-step guide for both LSL markers and hardware triggers with Brain Products and various stimulus presentation software programs that will ensure you are ready to start your experiments with the most accurate timing possible.
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.
So far, this series covered hyperscanning with BrainAmp amplifiers as well as with CGX Quick headsets. Part 3 introduces a more general approach, which is based on LabStreamingLayer (LSL).
When analyzing EEG data, especially event-related potentials (ERPs), a reliable relationship between event markers and actual events is crucial. This article introduces the means to measure timing delays and latencies in your EEG recording setup.
Brain Products has been a big supporter of LabStreamingLayer (LSL) right from the very beginning. Since then, LSL has become a well-established tool for the EEG research community and beyond. To continue and improve our support for this system we provide a venue where interested researchers can easily find all the necessary tools and information.
In case you missed our most recent blog post on BCI+, here is a quick introduction to our new BrainVision LSL Viewer and a complete data processing pipeline using LSL.
Curious about combining EEG and fNIRS for your mobile research? If the answer is yes, then check out our step-by-step guide on mobile EEG-fNIRS setup with LiveAmp, actiCAP slim/snap, and NIRSport 2.
We have created a website to show our solutions for the BCI+ field. On www.bci.plus you find our full range of BCI+ solutions including our amplifiers and electrode systems. We give information on toolbox integrations and will collect blog posts with BCI+ examples. With our BCI+ solutions we support the wider field of BCI-related technology.
LiveAmp joins the Brain Products family of amplifiers (BrainAmp, actiCHamp and V-Amp) that can be used by the open-source community. This article shows how to use LiveAmp in OpenViBE, BCI2000 and LSL open-source frameworks.
In the world of EEG, a closed loop application is typically interpreting/analyzing incoming EEG data and as a consequence of the analysis controls either Software or Hardware. A current hot topic in the neurophysiological research community are closed loop applications for brainstate dependent stimulation. Here obviously fast access or “real time access” to EEG data is the desire to precisely place the stimulation at the desired brainstate.
