... membrane potential change in the CG neurone. These results suggest that the CG neurones drive the myocardium by graded neuromuscular transmission in addition to impulse-mediated transmission in the heart of Ligia exotica . * Present address: Department of Biological Sciences, University of Calgary...

...Akira Sakurai; Akihiko Mori; Hiroshi Yamagishi ABSTRACT Neuromuscular transmission between the cardiac ganglion (CG) and the myocardium was examined in the adult heart of the isopod crustacean Ligia exotica . Intracellular injection of neurobiotin into the CG neurones revealed that all six CG...

... of neuromuscular transmission in the locust extensor-tibiae muscle has parallels with some of the modulatory effects of octopamine ( Evans and O'Shea, 1977 ; O'Shea and Evans, 1979 ; Evans, 1981 ; Evans and Siegler, 1982 ) and of the neuropeptide FMRFamide ( Evans and Myers, 1986 b ) in this preparation. Like...

...Hiroshi Washio ABSTRACT Functional changes in neuromuscular transmission following denervation of the coxal depressor muscle of the cockroach Periplaneta americana have been studied by intracellular recording. Miniature postsynaptic potentials, both excitatory (MEPSPs) and inhibitory (MIPSPs...

... and dose-dependence similar to its effect on the intact heart. The amines also enhanced neuromuscular transmission, with time course and dose-dependence similar to their effects upon the intact heart. The amplitude of unitary excitatory junction potentials (EJPs) and frequency of miniature excitatory...

... 11 1984 © 1985 by Company of Biologists 1985 Coelenterate neuromuscular transmission epithelium Aglantha digitale is a hydrozoan medusa with a rapid escape swimming response which consists of multiple contractions of the entire bell-shaped subumbrellar muscle sheet...

...Hiroshi Washio; Takenori Miyamoto ABSTRACT The effect of extracellular lanthanum on neuromuscular transmission was studied in cockroach leg muscle and larval mealworm ventral muscle by means of microelectrodes. Miniature excitatory postsynaptic potential (MEPSP) frequency was markedly increased...
