Figure 1

The biphasic relaxant response of bovine intraocular long posterior ciliary artery rings to EFS (10–18 V, 0.3 ms pulse width, 10 s train length, 16 Hz). The first solid line indicates the onset of stimulation; the second (at 10 s) represents both the end of the stimulation period and the peak of the first component of relaxation. The third line (at 50 s) indicates the peak of the second component of relaxation. (a) The control biphasic response. (b) The first component of relaxation was inhibited by L-NAME (100 μM), but the second was not. (c) Both components were abolished by TTX (0.1 μM).
