The neurons generating resting discharge in postganglionic neurons are constantly apprised by activity of aortic baroreceptors. We evaluated influence of denervation of baroreceptors on appearance and size of parameters of shared input accompanied with reciprocal activation observed in activity of sympathetic renal fibers of anaesthetized rabbits. The number of examined interaction was significantly reduced an hour after baroreceptor deafferentation in comparison with control conditions (χ2=5.738; P=0.017). However the evaluation of value of parameters of cross-correlation (width of shared input, height of shared input, mean amplitude and width of reciprocal activation and the distance between peaks) carried out during intact baroreceptor innervation and one hour after severing aortic nerves did not show any significant differences.
