The Different Mechanisms of Action Potential Propagation in the Heart
It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...

متن کاملThe Compound Action Potential (CAP) of the Frog Sciatic Nerve
a) In mammals, large peripheral nerves, for example the vagus, the sciatic and the ulnar typically are bundles of thousands of individual axons enclosed in a loose connective tissue sheath, the Epineurium. Within the Epineurium, the axons are grouped in fascicles, encased in a more structured epithelial sheath (the perineurium). Each axon is surrounded by a thin connective tissue sheath, the en...
متن کاملUncertainty Propagation in Nerve Impulses Through the Action Potential Mechanism
We investigate the propagation of probabilistic uncertainty through the action potential mechanism in nerve cells. Using the Hodgkin-Huxley (H-H) model and Stochastic Collocation on Sparse Grids, we obtain an accurate probabilistic interpretation of the deterministic dynamics of the transmembrane potential and gating variables. Using Sobol indices, out of the 11 uncertain parameters in the H-H ...
