Figure 6:

Pathwise equivalency of 14D HH model and Fox and Lu's model. (A) Given a sample path of the 14×28D Langevin model in equation 4.16, we construct the noise by equation 4.18 and generate the sample trajectory of Fox and Lu's model using equation 4.17. (B) Given a sample path of Fox and Lu's model in equation 4.17, we construct the noise by equation 4.24 and generate the sample trajectory of the 14×28D Langevin model using equation 4.16. For both cases, we plot the voltage V, the open probability of the Na+ channel (M31), and the open probability of the K+ channel (N4). We obtain excellent agreement in both directions.

(A) Given a sample path of the $14 \times 28$ D Langevin model in equation 4.16, we construct the noise by equation 4.18 and generate the sample trajectory of Fox and Lu's model using equation 4.17. (B) Given a sample path of Fox and Lu's model in equation 4.17, we construct the noise by equation 4.24 and generate the sample trajectory of the $14 \times 28$ D Langevin model using equation 4.16. For both cases, we plot the voltage $V$ ⁠, the open probability of the Na $^{+}$ channel (⁠ $M_{31}$ ⁠), and the open probability of the K $^{+}$ channel (⁠ $N_{4}$ ⁠). We obtain excellent agreement in both directions.
