摘要：

The new technique of magnetoencephalography (MEG) allows dynamic measure, that records the ongoing process of the brain with precise temporal resolution. Spontaneous magnetic slow (2-6Hz) and fast (12.5- 30Hz) activity can be used to locate the underlying sources with sufficient accuracy by using the single current dipole model. In this study spontaneous slow and fast MEG activity was measured in three schizophrenic patients with auditory hallucinations. We found a significant increase of fast activity compared to healthy probands in schizophrenics over the left and the right hemisphere dependent on handedness.
