Simultaneous EEG-fMRI - from acquisition methods to application
|Dates:||8 February 2012|
|Times:||12:30 - 14:30|
|What is it:||Seminar|
Speaker: Dr Karen Mullinger
Lunch from 12.30
Combining electroencephalography (EEG) with functional Magnetic Resonance Imaging (fMRI) in simultaneous recordings offers a unique capability to monitor brain function with high spatial and temporal resolution. The successful exploitation of EEG-fMRI is remarkable given the very large artefacts that are generated in the EEG data recorded during concurrent fMRI. Here Karen will outline the methods that have been developed to reduce these artefacts during data acquisition and also to improve correction techniques. These methods improve the quality of the EEG data that can be obtained in the MR environment, increasing the applications of this multi-modal technique. Karen will demonstrate one powerful application of high quality simultaneous EEG-fMRI data in understanding neurovascular coupling in positive and negative BOLD regions.
Since completing a BSc in Physics with Medical Physics 7 years ago Karen has gained unique and wide-ranging experience in the development and application of simultaneous EEG-fMRI working with the first MR-compatible EEG system at the Sir Peter Mansfield Magnetic Resonance Centre, Nottingham. This has involved collaboration with academic and industrial research leaders.
Karen's PhD addressed many aspects of simultaneous EEG-fMRI recordings including: improving EEG artefact correction, reducing artefacts at ultra-high field to make simultaneous recordings feasible, and identifying the major sources of MR image distortion due to EEG hardware. Subsequently, as a Sir Peter Mansfield Research Fellow, she has played a leading role in research aimed at understanding the origins of the gradient and pulse artefacts in EEG data, as well as in the development of beamformer techniques for localising EEG sources in EEG-fMRI experiments. Most recently, Karen has exploited the techniques we have developed to investigate neurovascular coupling via correlation of fMRI and EEG signals, in collaboration with Birmingham University’s School of Psychology.
