Research activities

Our core research activities focus on developing new methods, analysis techniques and software to promote MEG/EEG as a genuine functional brain imaging modality. The unique, superlative time resolution of MEG makes it a challenging endeavor, because of the high-density and multi-dimensional aspects of the data (3D space, time, frequencies, connectivity bonds between brain areas, etc.). This page briefly summarizes our methodological research and the clinical research projects we are developing with collaborators on and beyond the campus and the hospital partners. 


   

 Current Research Projects


Functional image reconstruction from MEG/EEG data with coregistration with MRI

Inverse image estimation, modeling, statistical appraisal.

Advanced methods for the characterization of dynamics of cortical current flows

Optical flow techniques adapted to arbitrary surface manifolds; Helmoltz-Hodge decompositions.

Detection and characterization of neuromodulatory effects of Cortical and Deep Brain Stimulation (CS, DBS)
