MRI+X: Improving Signal Quality in Combined MRI and EEG Recordings

Investigation of novel conducting materials for the concurrent measurement of the electroencephalogram and magnetic resonance imaging.

Overview

Runtime: 07/2016 to 12/2016

Funded by Uni-Freiburg Research Innovation Fund

Description:

Concurrent functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) recordings  combine the strengths of high spatial and temporal resolutions and provide a unique value for the investigation of cerebral function. However, the applicability of EEG-fMRI is very limited, as the EEG suffers from large artifacts induced by the MR environment caused by movements of the EEG hardware components within the magnetic field making the EEG largely uninterpretable. The MRI+X project will overhaul concurrent EEG-fMRI recordings by (a) objective EEG signal quality metrics based on BCI paradigms and machine learning data analysis, (b) optimized EEG hardware configurations, (c) novel conducting materials to replace standard EEG recording components to intrinsically reduce susceptibility to artifacts, and (d) adapted post-processing artifact reduction methods. We expect considerable improvements in the quality of EEG recordings inside the MR scanner, which will allow concurrent EEG-fMRI to gain much more widespread use.
