| Zusammenfassung | Modulation DC-magnetoencephalography is a tool to measure slowly changing magnetic fields of the brain by modulation the position of the head with respect to a sensor. The time resolution of this method is limited by the modulation frequency. By a respective random shift of the signal onset with respect to the modulation phase the time resolution can be improved significantly. This procedure is validated by parametric synthetic data derived from experimental data of modulation DC-magnetoencephalography. |
