✦ Synopsis
Application of octopamine
or lop5 M) to ventrally dissected hellgrammites increased the frequency of the ventilatory rhythm 16.6 2.0%. Similar results were observed when a chain of abdominal ganglia was isolated from other parts of the central nervous system and the periphery; thus, the effect was a central one. A ventilatory increase of similar magnitude was not elicited from chains of ganglia that lacked the dominant oscillator for the ventilatory rhythm; thus, exogenous octopamine acts at the expected site of physiological control of the rhythm. Dopamine or M) decreased ventilatory frequency 16.7 k 4.0%. Thus, as in other animals (Livingstone et al., 'go), a pair of amines has opposite effects on an invertebrate behavior.
