How to verify timing in your EEG setup

by Dr. Alex Kreilinger Strategic Product Manager (Brain Products) Before starting a study that involves EEG recording, it is always a good idea to make sure the setup, including software and hardware, works as planned to avoid any unwanted surprises once it’s time to analyze the recorded data. Unfortunately, it is not always obvious if…

Figure 2. How to position the BrainAmp MR (plus) system inside the scanner bore. Part A shows a BrainCap MR with CWLs inside a head coil, the top part of the head coil is removed to show the dedicated space for the EEG cable tree. 10 cm bundled cables are used to connect the EEG cap and CWLs to the amplifiers. Part B shows the full head coil and the BrainAmp MR plus and PowerPack positioned behind the head coil on a platform inside the scanner bore. A 30 cm ribbon cable is used to connect the EEG cap to the amplifier.

Safety tips for our new EEG-fMRI solutions

by Dr. Tracy Warbrick Application Specialist EEG-fMRI (Brain Products) In this article we provide an overview of our EEG-fMRI safety recommendations especially with respect to our recent developments. We will consider our sequence guidelines and what limits apply to our various caps. We will also provide an overview of recommendations for setting up the system…

Recording the same example sine wave with different sampling rates (= time resolution) and amplitude resolution. The necessary amount of accuracy depends on the Amplitude, signal-to-noise ratio and frequency of the signal of interest. Please note that the differences depicted here are exaggerated and will be much less noticeable with real data recorded from BrainAmp, actiCHamp, or LiveAmp.

Multicenter studies with different hardware – what to look out for

by Dr. David Schubring Scientific Consultant (Brain Products) Joining different labs to run the same study protocol has many advantages, e.g., including more participants from more diverse demographic and geographic backgrounds, comparing results between labs, benefiting from networking and knowledge transfer between colleagues, and ultimately a better generalizability of the results. On the other hand,…
