Abstract
Ionic selectivity of the channel for monovalent ions is too high; Li+, Na+ and Cs+ are practically impermeant ions. Permeability of the channel for Rb+ is .apprx. 10 times less; for Tl+ it is 2 times more than the permeability for K+. The open K+ channel has 16 multiple conductance levels.
