MEG and EEG

Magnetoencephalography (MEG) and electroencephalography (EEG) are  methods of studying the human brain function non-invasively using extracranial measurements of magnetic fields and electric potentials, respectively.  Different from functional magnetic resonance imaging (fMRI), MEG and EEG are directly sensitive to neuronal activities and both have a millisecond temporal resolution.

Our lab is interested in developing MEG and EEG methods in order to better understand how human brain works. Specific projects include MEG/EEG source localization, neuronal oscillations, and multi-modal imaging integration (MEG/EEG/MRI).
