[Do encephalo-electric signals determine the pulse frequency in man?].

One of the most interesting problems in EEG analysis is the question of the genuine generator of these biosignals. Each spontaneous EEG sampled by surface electrodes looks like a summary of stochastically distributed encephalo-electrical events. But analysing these data depending of the time distance of ECG R-waves we found signals which contain the information about the occurrence of the next ECG R-wave. The results make dubious the discussion about the autonomic character of sinus excitation as the heart pacemaker.
