Neural Electrotonus: Passive Signals Explained
Electrotonus: The Passive Spread of Electrical Signals in Neurons The Core Definition of Electrotonus Electrotonus refers to the passive spread of electrical current across the membrane of an excitable cell, typically a neuron, following a subthreshold stimulus. Unlike the active, regenerative propagation of an Action Potential, electrotonic potentials are fundamentally graded, meaning their amplitude is […]
