Examples

  • 2013, Thomas D. White, The Demonstration and Measurement of Adenosine Triphosphate Release from Nerves, David Paton (editor), Methods in Pharmacology, Volume 6: Methods Used in Adenosine Research, page 47, The veratrum alkaloid, veratridine, depolarizes excitable tissues by activating the Na+ channels present in the cell membranes. Therefore, one would expect veratridine to produce a depolarization of nerve that is quite similar to physiological depolarization insofar as it is mediated by changes in Na+ conductances.
  • 2013, Domingo M. Aviado, The Lung Circulation, Volume 1: Physiology and Pharmacology, page 39, The results from veratridine will be described first because they illustrate the ultimate way of obtaining proof that the carotid sinus baroreceptors can respond to foreign chemical agents.
