Effect of AMRPs on contractions of other muscles in Aplysia. A, Effect on electrically induced contraction of the penis retractor muscle. Repetitive electrical pulses (20 V, 1 msec, 40 Hz, 40 pulses) were applied to the muscle at 10 min intervals. Peptides (10−8m) were applied for 9 min. B, Effect on electrically induced contraction of the dorsal longitudinal muscle of the body wall. Electrical pulses (20 V, 2 msec, 100 Hz, 20 pulses) were applied at 10 min intervals. Peptides (10−7m were applied for 9 min.
