The Nervous System
... Stimulation causes the membrane of a neuron to open the Na+ ion channels allowing Na+ ions to rush into the cell This causes the local area of the neuron to become positively charged (depolarized) Depolarization causes the Na+ ion channels to close and the K+ channels to open Diffusion of K+ ions ou ...

... Volts/meter. When an action potential travels down the axon, deviations from this resting potential in the order of 100 milliVolts occur, causing a strong change in electrical field strength over this membrane. It is our hypothesis that this change in electrical field causes small mechanical deforma ...
