Feasibility of clinical Magnetoencephalography (MEG) functional mapping in the presence of dental artefacts

► State-of-the-art MEG signal processing techniques enable the removal of artefacts introduced by orthodontic braces. ► Localisation accuracy of SEF and motor responses is comparable in subjects wearing and not wearing braces. ► MEG can be used for pre-surgical evaluation in a much larger clinical population than previously thought possible.
