Figure 4. Afferent responses to increase in intra-arterial pressure.

A, mesenteric afferent firing evoked by increasing the intra-arterial pressure from 5 mmHg to 60 mmHg. B, mean firing rates (Hz) over the 20 s before vs. 20 s immediately after intra-arterial pressure was increased from 5 mmHg to 20, 40, 60 or 80 mmHg (n = 9, N = 5, F(1,3) = 14.74, P < 0.05). C, average firing rate, in 10 s bins, at 5 mmHg (2 min) and 60 mmHg (2 min) (n = 9, N = 6).
