Abstract
Various investigators have reported the presence of slow or fast rhythms in efferent sympathetic discharges. The slow rhythms are usually locked to the central respiratory rhythm, as demonstrated by analysis of rectified and integrated versions of phrenic and sympathetic discharges (Barman and Gebber 1976; Cohen and Gootman 1970). As seen in cycle-triggered histograms (CTHs), the most common pattern of sympathetic discharge consists of augmented firing during the central inspiratory (I) phase and reduction of activity below the tonic level during the early expiratory (E) phase. Moreover, the respiratory-related component of sympathetic discharge is strongly inhibited by lung afferent input (Gootman et al. 1980).
