Magnetoencephalography (MEG) and functional magnetic resonance imaging (FMRI) were applied to brain mapping in three normal volunteers and three patients with brain tumors. The central sulcus was identified by source localization of the somatosensory evoked potentials (SEFs) in all subjects. Functional abnormality was detected as reduced amplitude or latency delay of the SEF peaks. FMRI indicated multiple and extended regions of activation, such as primary motor, primary sensory, and supplementary motor cortices. The primary motor and sensory cortices were not activated due to the effect of the lesion of one patient. The highest activation was found far posterior to the central sulcus due to a large venous inflow effect in another patient.
