This study was carried out on sympathetic renal fibers of anaesthetised rabbits. Shared input assessed by cross-correlation analysis was found in 159 pairs of neurons in control conditions and in 128 during increased blood pressure. The width of cross-correlogram peak was 237.57±5.54 ms in control conditions and 249.97±7.13 ms during elevated blood pressure. The peak height was respectively 4.03±0.14 spikes/s and 4.39±0.23 spikes/s. Geometric mean of frequency of discharge of neuronal pairs was 1.17±0.04 spikes/s and 0.93±0.04 spikes/s. Geometric mean of cardiac modulation was weak 33.56±1.18% and significantly correlated with geometric mean of frequency of discharge and correlogram width in control conditions. The respiratory modulation of pairs of neurons was strong – respectively 78.63±0.85% and 88.29±0.95% – and was significantly related with geometric mean of frequency of discharge, correlogram width and peak height in resting conditions.
