On the conduction velocity of nonmyelinated nerve fibers.
Nerve impulse conduction in nonmyelinated nerve fibers is analyzed by considering this process as a direct consequence of the coexistence of two structurally distinct regions, active and resting. Assuming that the active (i.e. swollen) region of the fiber is in direct contact with the resting (i.e. shrunken) region, a simple procedure for deriving the conduction velocity equation is described. The physico-chemical significance of the quantities in this velocity equation is briefly discussed.
