Project Title: Reconstructing and Understanding Cortical Dynamics from Multimodal Brain Imaging Methods

Project Abstract:

The overall goal of this proposal is to develop methods for combining multimodal brain imaging data for improved estimates of neural activity. Magnetoencephalography (MEG), electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) are popular noninvasive neuroimaging techniques with complementary temporal and spatial properties. Neuroscientists are increasingly interested in performing experiments using both modalities and therefore need a biologically and statistically sound method of combining the data. To assist creation of such methods, the relationship between the neuromagnetoelectric signals measured in MEG/EEG and the neurovascular signals measured in fMRI needs to be better understood through experimental manipulations.
