Abstract

The aim of this study was to compare MEG and fMRI localisations of primary sensory-motor cortex, in normal subjects and patients scheduled for neurosurgery. The study is a precursor to the development of a pre-surgical map** program. The results indicate that in both normals and patients, fMRI and MEG localisations are confirmatory and match well with localisations obtained during surgery. However, in one subject, the MEG localisations were displaced significantly from the central sulcus. We discuss the implications and possible generating mechanisms of this displacement.
