Fig. 8. (A,B) Neither of the two action potential (AP) classes was significantly
influenced by amine injections. The frequencies of small and large action
potentials were evaluated for segments 10 min in duration within 30 min before
(
before) and after (after) drug injections, and
the normalized frequency after/before was
computed. For comparison, data segments of 10 min, separated by 40-50 min, but
without any injection, were analyzed the same way. One-way analysis of
variance (ANOVA) did not reveal significant differences between any dose of
the injected drugs, the control (injected with haemolymph Ringer) and the
non-injected state. Values are medians + S.E.M. Values of N given in
A also apply to B. 5-HT, serotonin; OA, octopamine; HLR, haemolymph
Ringer.
