“…In order to determine Cli for varying Ko, we obtained Em from a study that examined the dependence of Em on Ko (Somjen et al, 1981) -the dashed line in Fig. 5C is adapted from that study and demonstrates the change in Em with varying Ko e and calculated Cli for specific Ko concentrations using the formula above and the previously determined value of the factor a.…”

“…is now well documented for a wide variety of excitable cells. These cells include the squid giant axon (Curtis & Cole, 1942;Hodgkin & Huxley, 1945), neurones in the leech nervous system (Schlue & Deitmer, 1984), the vertebrate node of Ranvier (Huxley & Stampfli, 1951 a, b), and mammalian dorsal root ganglion cells (Somjen, Dingledine, Connors & Allen, 1981).…”

“…Although there has been considerable interest in the effects of extracellular accumulation of K+ ions on neurones in the central nervous system (CNS) (see reviews by Somjen et al 1981;Sykova', 1983) the only studies on the effects of different extracellular ionic concentrations on the membrane potential of CNS neurones have been on amphibian spinal motoneurones (Sykova' & Orkand, 1980) and in cultured mouse spinal cord neurones (Hosli, Andres & Hosli, 1972). The experiments described here were carried out on spinal motoneurones of the young rat using an in vitro preparation (Otsuka & Konishi, 1974;Fulton, Miledi & Takahashi, 1980).…”

“…Indeed, this assembly has been used when the measurement takes place in excitable tissues, because the effect caused by the locally generated electrical potentials were thus minimized. 21 Although this is not true in all cases, for instance, nerve spike potentials cannot simply be canceled, 22 it seemed worth to examine in more detail the applicability of these assemblies in corrosion science.…”
