Fig. 8. CabTRP Ia increases contraction of the gastric mill 8 (gm8) muscle. (A) The lateral ventricular nerve (lvn) was stimulated at 10 Hz for 3 s, and the resulting contractions of a gm8 muscle in control saline (black), after 10 min in 10^–7 mol l^–1 CabTRP Ia (red), and after rinsing the peptide (green) are shown. (B) A bar graph of average gm8 peak contraction amplitude in control saline and after 10 min in10^–7 mol l^–1 CabTRP Ia. The increase in amplitude in peptide was significant (N=7; paired t-test, **P<0.01).
