Abstract: | The drug 2(4-phenylpiperidine)cyclohexanol (AH 5183) caused hyperpolarization by 1.8 +/- 0.6 mV in an end-plate zone of mouse diaphragm fibers without any change in the amplitude of miniature end-plate potentials. This supports the idea that the drug inhibits the non-quantal leakage from motor nerve terminals, probably at those parts of the nerve terminals which were incorporated into the terminal membrane after vesicle exocytosis. |
