[Functional characteristics of potassium channels in the somatic membrane of neurons of Lymnaea stagnalis of various ages].
It has been found that in old Lymnaea stagnalis neurons the maximal amplitude of the delayed potassium current and the maximal potassium conductance decreases and the kinetics of inactivation of the delayed outward current slows down. It is suggested that these changes may be associated with the age peculiarities of the phospholipid composition of membranes and not related to shifts in the surface area of the nerve cell during aging. The age dependence of the function of potassium channels may underlie the changes in the neuronal function during aging.
