The combination of electroencephalography (EEG) and functional MRI (fMRI) is very compelling to study the functioning of the human brain thanks to the high complementarity of electric and hemodynamic signals. Despite the technical challenge of recording sensitive signal of EEG into the strong magnetic field environment of the MRI, this non-invasive multimodal technique is now widely used in the neuroscience to study the spatio-temporal brain dynamics. In this webinar, I will present the challenges associated with concurrent acquisitions of EEG and fMRI. I will describe the safety concerns and the different interactions between EEG and fMRI. Then, I will give an overview of some applications of simultaneous recordings in clinical and cognitive neurosciences at different field strengths.

Discussion points of the webinar:

  • What are the safety issues associated with a simultaneous acquisition of EEG and fMRI?
  • What are the effects of the static magnetic field and of the gradients on the EEG recording?
  • What are the challenges for a simultaneous EEG and fMRI acquisition at Ultra-High Field?

Frédéric is a research staff scientist in the CIBM MRI UNIGE Cognitive and Affective Neuroimaging Section. He is in charge of the operational functioning and the methodological development of the MRI platform located at the Brain and Behaviour Laboratory at the Medical University Center of the University of Geneva. His main research interests are multimodal imaging (e.g. EEG-fMRI) to better characterize the spatio-temporal dynamics of the brain functions, the development of advanced techniques for pre-operative brain mapping and the integration of Virtual Reality with bi-modal neurofeedback to open up new clinical therapy in particular in children with neurological or psychiatric disorders.
