| Title in another language: | localisation of focal slow wave activity in depression |
| Summary: |
Focal slow wave activity in spontaneous MEG has been associated with neuropathology. Slowing of spontaneous MEG has also been reported in various psychiatric diseases. Especially EEG studies have shown increased slow wave activity in schizophrenic patients mainly in the delta range. The aim of this study was to localise focal slow wave activity in the delta (1.5Hz-4Hz) and the theta (4Hz-8Hz) bands using a dipole density method in patients with a DSM-IV diagnosis of affective (depressive) disorder. The main finding was that depressives displayed less generators of focal slow wave activity than controls in prefrontal brain regions.

| Summary in another language: |
Fokale langsame neuromagnetische Gehirnaktivität wurde bisher mit neuropathologischen Erscheinungen in Zusammenhang gebracht. Eine Verlangsamung spontaner MEG-Aktivität wurde auch bei psychiatrischen Patienten beobachtet. Besonders in EEG Studien wurde eine erhöhte langsame Aktivität vornehmlich im Deltaband bei schizophrenen Patienten festgestellt. In dieser Studie sollte fokale langsame Aktivität im Delta- (1,5-4Hz) und Thetaband (4-8Hz) mit einer Dipoldichte-Methode bei depressiven Patienten lokalisiert werden. Hauptsächlich zeigten depressive Patienten weniger Generatoren fokaler langsamer Aktivität als Kontrollprobanden in präfrontalen Gehirnregionen.
