title: K+-loss of frog nerves during electric stimulation.
abstract: Proximal section of nervus ischiadicus of frog was directly stimulated, and distal section of the same length was stimulated indirectly. Indirect stimulation resulted in a 2 per cent loss of K+ content, direct stimulation caused a loss of 31 per cent of the K+ content. Indirect stimulation does not cause a significant K+ efflux; direct stimulation results in a significant decrease in K+ content even at a probability level of p=0.001. A correlation was found between the changes in the K+ content of frog nerve and the intensity of the applied electric impulses. The decrease of K+ content of frog nerves is in ratio with the logarithm of stimulation voltage.
