Abstract
.We introduce a method of combing MEG and fMRI to generate estimates of synchronized oscillations on the cortex. This method suppresses locations without concordant fMRI activity to avoid over estimation of phase-locking values. Simulations suggest 80% fMRI provides optimal detection power. We demonstrate this method in human somatomotor data to characterize beta-band oscillations.
