  • Abstract
  • Look Inside

A concurrent recording of electroencephalogra-phy (EEG), magnetoencephalography (MEG) and electromyography (EMG) was carried out in a patient with epilespia partialis continua. He had continuous clonic jerks in his right hand and fingers. The EMG electrodes were placed on the thumb of his right hand. We observed numerous MEG spikes in the left central region and about half of them were accompanied by EMG potentials with a latency of about 20 msec. The EEG spikes appeared less frequently, had low amplitudes, and had unclear morphologies and further, no clear association with EMG potentials.
