Different modes of dampening influence from baroreceptors are determined by the functional organization of the NTS neuronal network.
Simultaneous recordings of several neurones of the first relay station of baroreceptor afferents show that its general activity-dampening influence is realized via the common brainstem system (CBS) which itself controls the processing on the neurones of the nucleus of the solitary tract (NTS). This feedback system maintains the degree of activity which is necessary for the ongoing behaviour as long as it fits to the environmental situation. The output of the NTS is determined partly by the CBS, partly by the properties of the peripheral afferent input, partly by the dynamic functional organization of the local circuits and partly by influences from other brain areas.
