| Zusammenfassung | A non-invasive DC-electroencephalographic (DC-EEG) method was developed to record and to analyze focal low frequency ((0.1 Hz) DC-changes in the human cerebral cortex. As an exemplary physiological activation paradigm a repetitive simple finger movement task was used. DC-EEG amplitudes were recorded using a custom-made DC-amplifier with automatic offset correction. 16 standard Ag-Ag/Cl electrodes covered the left primary motor cortex. In 3 of 6 subjects reliable focal motor-related DC-EEG shifts over the hand cortex were monitored. This study demonstrates that refined DC-EEG recording and data analysis procedures allow recording non-invasively low-frequency and low-amplitude focal cortical changes in humans. An important clinical perspective of this technology is the detection of stroke associated cortical DC-activity. |
