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…

Figure 2. An example of a head coil with a specific EEG cable tree routing option. The cable tree from the BrainCap MR runs in a straight line directly from the top of the volunteer’s head. In this case, the head coil is the Siemens Head/Neck 64 coil

Changes to the BrainCap MR

by Dr. Tracy Warbrick Application Specialist EEG-fMRI (Brain Products) The BrainCap MR has been the preferred choice for simultaneous EEG-fMRI research for more than a decade, but advances in fMRI technology mean that it needs an update. We have made some changes to the standard BrainCap MR cable lengths to improve the user experience and…
