To correct this, let me replace the jot in any Venn symbol (1) by 1 if the jot is always present, by 0 if it is always absent, and by p if it is present with a probability p due to a shift of the threshold 0 of...

Resting squid nerve membrane actively extrudes Na+ against a large concentration gradient, while another cation, K + , is concentrated passively within the cell by the Donnan equilibrium. During the passage of an impulse, large transient current flows across the membrane; some K + leaves, some Na + enters, but which ions carry the current at which instant, and how it is turned on and off cannot...
