Physiology and ultrastructure of electrotonic
In the present study we established the dependencies of experimental values of space constants of electrotonic decay along ([[lambda].
The results of modeling of electrotonic potential distribution in two-dimensional resistive medium.
Stimulation with a depolarizing current pulse in any one cell simultaneously initiated DPs in all; the amplitudes and form differed slightly, but remained characteristic in each cell, hence indicating that the DP represented an active response of each neuron, but one that was brought to threshold by the spread of the depolarizing s timulus via pervasive electrotonic coupling among all neurons of the ganglion.
The coordinated response of the entire ganglion to such perturbation of a single neuron is ensured by the combination of electrotonic and probably reciprocal excitatory synaptic interactions among all the cells.
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.
This innervation, along with tight electrotonic
coupling between individual muscle fibers, ensures rapid spread of excitation throughout the myocardium, resulting in strong, coordinated contraction of the ventricle with each burst from the CG (Kuramoto and Kuwasawa, 1980).
