Abstract(in English) | Functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) are the major recording means of brain activity. FMRI records brain activity with high spatial resolution but its temporal resolution is low due to slow hemodynamic responses to neural activity. Conversely, MEG has characteristics that the temporal resolution is high but spatial resolution is low. One of the solution is combining both records of fMRI and MEG so that we can estimate high spatio-temporal brain activity. However, taking into consideration the measurement cost and the burden on the subject, it is difficult to obtain high quality measurement data of both modalities. Therefore, we propose combining MEG data with meta-analysis fMRI instead of measured one. And also, we developed realistic simulation framework to evaluate our proposal. |
