Abstract
In this article, we present the clinical indications and
advances in the use of magnetoencephalography to map the
primary sensorimotor (SM1) cortex in neurosurgical patients
noninvasively. We emphasize the advantages of
magnetoencephalography over sensorimotor mapping using
functional magnetic resonance imaging. Recommendations to the
referring physicians and the clinical magnetoencephalographers
to achieve appropriate sensorimotor cortex mapping using
magnetoencephalography are proposed. We finally provide some
practical advice for the use of corticomuscular coherence, corticokinematic
coherence, and mu rhythm suppression in this
indication. Magnetoencephalography should now be considered
as a method of reference for presurgical functional mapping of
the sensorimotor cortex.
