Sensorimotor mapping allows separation of the brain’s representation of individual digits. This is possible using functional magnetic resonance imaging (fMRI), but is more challenging in magnetoencephalography (MEG) where it has been demonstrated by mapping evoked responses. Here, we use ultra-high field (7T) fMRI to map digits in a finger-tapping experiment, and contrast our findings to equivalent results showing the spatial signatures of beta band oscillatory responses measured in MEG. We show that the MEG beta rebound can be mapped topographically.
