The effect of emymatic proteolysis on structural and functional properties ofthe isolated lobster nerve membrane was investigated. The membranes were treated with diffcrcnt amounts of either trypsin or unspecific protease. Sodium channel activity was determined by measuring the veratridine-tetrodoto
## T W O FIGURES Thc well-known antagonism of calcium and potassium salts and certain aspects of the actions of these ions as chemical stimulants and depressants of the neuromuscular system suggested the investigation of the effect of varying the concentration of Ca++ on the potassium content of s
## T W O FIGURES Injury potentials are frequently interpreted as measures of ion permeability of cell membranes. I n particular, variations in such bioelectric potentials when the ionic environment of the cells is altered have been invoked as indices of permeability changes. Certain difficulties h
It has been shown (Blair, '32, '35, '38 a ) that the a excitability gives rise to a strength-duration curve which is approximately the same as that obtained from other excitabilities and that it is evidenced by the data of latent addition (Blair, '38 a ) that the kinetics of the excitation process a
