The membrane length constant describes how far an action potential can propagate along an axon. When current is injected into an axon, a. an action potential is evoked before the current has spread any distance from the point of injection.
What happens when current is injected into a cell?
In other words, when current is injected into the cell, most of this current is used initially to charge the membrane capacitance, which basically amounts to a certain amount of current being required to change the distribution of ions near the cell membrane.
Where does current move passively?
A current-passing electrode produces a subthreshold change in membrane potential, which spreads passively along the axon.
