FIG. 2.

(Color online) The spatial profiles of the action potential, the action-potential-induced electric field on the membrane, and the differential second-harmonic signal calculated along a myelinated nerve fiber (a) and at the nodes of Ranvier (b), located at x/L = 0, 1, 2, 3… (shown by circles), at the instants of time t = 0.2 ms (1), 0.4 ms (2), 0.6 ms (3), 0.8 ms (4), 1.0 ms (5), 1.2 ms (6), and 1.4 ms (7).

FIG. 3.

(Color online) The waveforms of the action potential, action-potential-induced electric field, and the differential second-harmonic signal calculated at the nodes of Ranvier with j = 0 (1), 5 (2), 10 (3), 15 (4), and 20 (5).

FIG. 4.

(Color online) The action potential, the AP-induced electric field, and the differential second-harmonic signal calculated at the nodes of Ranvier (shown by open and filled circles) at the instant of time t = 1.4 ms for a normal myelinated nerve fiber with δ myelin = 3 μm and D = 15 μm (solid line with filled circles) and a nerve fiber demyelinated ( = 0.5 μm and  = 10 μm) between the nodes of Ranvier with j = 7 and 12 (dashed line with open circles).

(Color online) The waveforms of the action potential, the action-potential-induced electric field, and the differential second-harmonic signal calculated for a nerve fiber demyelinated ( = 0.5 μm and  = 10 μm) between the nodes of Ranvier with j = 7 and 12 at the nodes of Ranvier with j = 0 (1), 5 (2), 10 (3), 15 (4), and 20 (5).

FIG. 7.

(Color online) Maps of the action-potential peaks at the nodes of Ranvier calculated for a three-neuron reverberating circuit, with each neuron including 25 nodes of Ranvier. The synapse end neuron excitation delay is 3 ms. The arrows show the direction of action-potential circulation around the neuron circuit.

(Color online) The waveforms of the action potential, the action-potential-induced electric field, and the differential second-harmonic signal calculated for the three-neuron reverberating circuit at the nodes of Ranvier with j = 5 (solid line), 10 (dashed line), and 15 (dash-dotted line) in each of the three neurons forming the circuit.
