Clinical MEG : Motor function disorder 2-3-1 : Auditory evoked fields in patients with advanced Parkinson ' s disease during deep brain stimulation

area of interictal magnetoencephalography. Then, we investigated the relationship between the magnetoencephalographycally abnormal area and the resected temporal lobe. Results: Repeated spikes were observed from only one patient, but no repeated spike from four patients during ictal state. Theta waves were observed from all five patients in this series. The repeated spikes were localized in the temporal base on the magnetic source image. The magnetic source origin of ictal theta waves analyzed by the spatial filter were estimated in the resected temporal lobe of all patients. The interictal magnetic source images indicated the resected temporal lobes. Conclusion: Ictal magnetoencephalography of the temporal lobe epilepsy was inclined to show the theta rhythm. In this series, the initial onset areas analyzed by the spatial filter were situated in the resected temporal lobes.
