An Experimental Study on BEM-Based Cortical Imaging of Human SEP Activities

Abstract

The boundary element method (BEM) based cortical imaging technique (CIT) has been applied to an experimental study on human somatorsensory evoked potentials (SEPs) recorded from a patient. The accuracy of the analysis was determined by comparing SEPs recorded from the scalp with those recorded directly from the patient's cortex. The results indicate that the CIT improved the spatial resolution of the scalp potentials, and the reconstructed cortical potential maps are consistent with the direct cortical recordings.
