Abstract

When voluntary movement occurs three components of neuromagnetic fields are seen: a readiness field from about 1.5 seconds before the start of movement; a motor field just before the start of movement; and immediately after the movement a movement evoked field. These waveforms are together called movement related cerebral fields (MRCF). There are many things which are still unclear about the significance of each waveform component of MRCF, and elucidating the source of the electric currents and the significance of each of the waveforms, and their practical application to motor learning and motor control is the subject of our research. At this seminar we would like to give a simple overview of neuromagnetic cortical activation, introduce three fields of research related to neuromagnetic mapping, as well as explain as far as possible the future direction of neuromagnetic mapping research.<br>
