Abstract :
The action potential event is explained, making use of a membrane model that includes an electromechanical action, such as electrostatic compression. The model shows the permeability modulation induced by potential changes and explains the ionic transfer phenomena (sodium input in the rising phase and the delayed output of potassium in the decaying phase). Other associated phenomena, such as accommodation, are also explained. It is necessary to consider the presence of an inhibition mechanism for the sodium transfer, probably associated with the transferred charge.<>
