TL;DRAbstract

More than 40 years of electrophysiological investigations of baroreceptor fibres in the carotid sinus nerve (starting with Bronk and Stella, 1932, 1935) have informed us relatively well about the general properties of these receptors. Their principal reactions — such as thresholds, proportional and differential sensitivity, maximum firing rates — were shown to be very similar to those of other slowly adapting mechanoreceptors (Landgren, 1952; for survey of the literature, see Heymans and Neil, 1958; Paintal, 1972). However, the mean response of the entire baroreceptor activity to pressure variations is still not sufficiently known, although it must be assumed to represent the relevant information for the reflex response as described by the well-known “Blutdruckcharakteristik” (Koch, 1931). The characteristics of this response could not be obtained from classical single fibre investigations, since variations from one fibre to another turned out to be considerable, and the number of fibr
