electrotonic conduction

the passive flow of a change in electric potential along a nerve or muscle membrane. It occurs in response to stimulation that is inadequate to trigger an actively propagated action potential (i.e., subthreshold stimulation) but instead generates depolarization in a small area of membrane. This localized depolarization travels to neighboring areas via the drifting fluid within the cell, rapidly attenuating as it spreads.

See also either–or fallacy; false analogy; false authority; false cause; historical fallacy.
