Abstract

The purpose of this pilot study was to test both the usefulness and reliability of a mapping method that was described in its most recent version by Rappels-berger et al. (1986). Unlike other mapping methods, this one takes into account coherence estimates. Up to the present time, it has been applied for extracting features characteristic of changes of the ongoing EEG due to cognitive tasks (Petsche et al. 1985, 1986; Pockberger et al. 1985). It turned out that the parameter “coherence” yields additional and valuable hints to how information is processed by the cortex.
