coupling between human atrial myocytes and fibroblasts alters myocyte excitability and repolarization," Biophysical Journal, vol.
Effect of transmural vagal stimulation on electrotonic
current spread in the rabbit sinoatrial node // Cardiovasc.
Although we did not observe an increase in the overall dispersion of repolarization, this may be the case for the larger hearts, such as human one, due to the lower electrotonic
cancellation of repolarization inhomogeneities in large myocardial volumes (7).
Moreover, electrophysiological studies have shown that the unmyelinated axons of SNs are efferent even though they emerge from the dorsal roots of the spinal cord and are coupled by electrotonic
junctions (2, 3, 4, 5, 6).
Moreover, the strength of electrotonic
interaction is primarily related to the magnitude of cellular coupling as determined by gap junctional conductance.

coupling of excitable and nonexcitable cells in the heart revealed by optogenetics," Proceedings of the National Academy of Sciences, vol.
For modeling the electrocardiosignal genesis and excitation wave spread in myocardium [1-3], values of the parameters of the passive electric properties of myocardium (such as resistivity of the intracellular medium, electrogenic membrane, intercellular contacts, space constants of electrotonic
decay) are essential.
The mechanism of rectification at the electrotonic
motor giant synapse of the crayfish.
Synchronization of ganglionic activity is not only mediated by synaptic drive, but the general excitability of the network is shared among all of the neurons by means of electrotonic
coupling capable of passing slow changes in potential.
Comparative physiological studies in the cunner and other teleost fish have indicated that these cells make electrotonic
connections with one another (2).
Comparative physiological studies have indicated that these cells in the cunner and other teleost fish make electrotonic
connections with one another, and that they respond to tactile inputs from the skin (4).
The spread of electrotonic
potentials was examined with heart preparations that had stopped beating after perfusion for several hours.
