A proposed dynamic mechanism of nerve action potential.
A molecular mechanism of nerve action potential is proposed, resting in two assumptions: (1) The voltage impulse is due to unequal flows of sodium current and potassium current. (2) Current flow is governed by the applied voltage, by a voltage-dependent dipole barrier, and by diffusional and frictional forces. It is suggested that the dipoles could couple with phonons in the membrane matrix so that upon voltage application the height of the dipole barrier would show a transient with a minimum.
