die Durchführung
- Continuous magnetencephalographic data were obtained by a 148 channel whole-head
magnetometer (Magnes ® WH 2500, 4D Neuroimaging, San Diego, USA)
-Offset and noisereducing procedures were performed on the raw data.
Data were reduced by factor 16 and bandpass filtered: delta [1.5-4.0 Hz], theta [4.0-8.0 Hz],
alpha low [8.0-10.5 Hz], alpha high [10.5-13.0 Hz].
Multiple Source Analysis (Minimum-Norm, L2-norm)
A 30 second data epoch low on artifacts was extracted out of each originally obtained 5-
minute data epoch.
Over each time point between a global field power of 3000 and 18000 [ft] that did not correlate with a typical eyeblink
pattern a minimum- norm solution was performed. All solutions were then averaged
