Figure 1From: Modulatory effect of adenosine receptors on the ascending and descending neural reflex responses of rat ileumRepresentative tracings showing the effect of the A1-receptor agonist CPA and the A1-receptor antagonist DPCPX on the (a) ascending excitatory reflex response and (b) descending relaxant reflex response in the rat ileum. The reflex response was induced by electrical stimulation (EFS; 20 V, 2 ms, 3 pps, 15 s), and the response was recorded by contractility recording 2 cm oral from the stimulation site.
