“…The power in the autospectra is usually concentrated in a narrow band around the heart rate (Barman, Gebber & Zhong, 1992; Kocsis, Fedina, Gyimesi-Pelczer, Ladocsi & Pasztor, 1993) and the peak coherence between the nerves is higher 687 2710 (Barman et al 1992). Furthermore, there is a significant linear component of the baroreceptor effect on the activity of different sympathetic nerves, which can be quantified by measuring the value of the coherence function between the nerve signal and the arterial blood pressure, at the heart rate (Barman et al 1992;Kocsis et al 1993). Thus, it is reasonable to expect that, in baroreceptor-intact cats, the nerve-to-nerve coherence.can, to some extent, be explained by the influence of the common periodic input from the baroreceptors.…”
