Summary
Different types of phase coupling between and within EEG signals are theoretically explained and coupling-related analysis strategies are reported. Effects of synchronization have been distinguished from effects signal transfer (propagation), where both are designated by a phase coupling. Six examples of phase coupling analysis are presented. The EEG data are derived from our previous investigations and analysis results are complemented by modelling and simulation studies.

Obituary: This article was conceived of as an overview of the development of our methodical strategies over the last ten years regarding time-variant phase couplings. After the first draft of the article was already completed, I received the inconceivable message that Dr. Bärbel Schack had passed away on the morning of July 24, 2003. I had the privilege of knowing Dr. Schack for more than fifteen years and I always regarded her as a personal friend. By her untimely passing, the Institute of Medical Statistics, Computer Science and Documentation has lost one of its ablest scientists. She was an internationally recognized scientist, a fine colleague and a faithful friend, and I am sure she will be greatly missed by all who knew her. Herbert Witte
