First Steps to Using Carbon Wire Loops to Correct for Artifacts in simultaneous EEG-fMRI

by Lars Hausfeld, PhD Department of Cognitive Neuroscience, Maastricht University, Maastricht Brain Imaging Centre (M-BIC) The Netherlands Abstract The simultaneous acquisition of EEG and fMRI signals promises linked datasets with high temporal and spatial resolution, respectively. To make optimal use of the data from this advanced acquisition scheme, the attenuation of artifacts in EEG signals…

Carbon Wire Loops in EEG-fMRI studies of interictal epileptic activity

by Nicolas von Ellenrieder, PhD, Andreas Koupparis, MD, Natalja Zazubovits and Jean Gotman, PhD Gotman Lab EEG, Imaging, and Epilepsy McGill University, Montréal, QC (Canada) At the Montreal Neurological Institute and Hospital, we work with combined EEG and fMRI acquisition to study epileptic patients to determine the brain region responsible for the generation of seizures…

Carbon Wire Loops for BrainCap MR

State of the art MR artifact handling with Carbon Wire Loops – a true market innovation!

by Dr. Tracy Warbrick and Dr. Michael Schubert Application Specialist EEG-fMRI and Product Manager (Brain Products) We are excited to let you know that Carbon Wire Loops (CWL) for the BrainCap MR are now available to order. Why Carbon Wire Loops? For EEG data acquired during fMRI scanning the gradient artifact and cardioballistic artifact are…

Easycap EEG recording caps: An overview

by Falk Minow General Manager (Easycap GmbH)     Despite some interesting new developments in the area of EEG Recording Caps like sponge-and-saltwater-nets or dry-electrode-headsets, the majority of EEG research is still done with electrolyte-gel-filled-electrode-caps. Easycap manufactures caps with any channel number, any layout and for connection to any amplifier. This is not only for…

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…
