Figure 8. Distension-evoked responses in circular muscle recorded intracellularly.

Figure 8

EJPs recorded at the oral end of one preparation (A) and IJPs recorded at the anal end of another preparation (B) when distensions were applied in the chamber adjacent to the recording chamber. Traces between A and B show onset and duration of distension stimuli. a, control responses; b, responses while UK14,304 (100 nm) was present in the stimulus chamber; and c, responses after wash out of the drug. Whereas ascending EJPs evoked in this way were depressed by UK14,304, IJPs recorded at a similar distance, but anally from the stimulation site, were not.
