“…4.1 B). The wave patterns observed in electrically stimulated actin filaments are remarkably similar to recorded solitary waveforms from various experimental studies on electrically stimulated nonlinear transmission lines (Kolosick et al, 1974;Noguchi, 1974;Ostrovskii et al, 1974;Bogatyrev and Fainshtein, 1976;Lonngren, 1978;Stewart and Corones, 1978). Considering the actin filament's highly nonlinear complex physical structure (Pollard and Cooper, 1986) and the thermal fluctuations of the counterionic cloud from the average distribution (Oosawa, 1970;Oosawa, 1971 C t3/ t1 20 FIGURE 3 (A) Schematic representation of the experimental setup.…”

“…An experimental proof for this interaction is heretofore unavailable. Functionally, actin polymers may thus serve as biological "electrical wires" and can be modeled as nonlinear inhomogeneous transmission lines able to propagate nonlinear dispersive waves and solitons (Kolosick et al, 1974;Noguchi, 1974;Ostrovskii et al, 1974;Lonngren and Scott, 1978). Actin filaments were observed and mechanically isolated in this report to enable the direct measurement of electrical signals from single polymers in solution.…”

Actin, one of the most abundant intracellular proteins, forms long linear polyelectrolytic polymers in solution. A novel technique to handle single actin filaments in solution was developed that allows the study of ionic currents elicited along the surface of electrically stimulated actin filaments. Electrical currents were observed about the polymer's surface under both high (100 mM KCl) and low (1 mM KCl) ionic strength conditions. The data are consistent with a dynamic behavior of the counterionic cloud surrounding the actin filaments that support ionic movements along their longitudinal axis upon electrical stimulation. Counterionic waves were highly nonlinear in nature and remained long after the electrical stimulation of the actin filaments ceased. In this report therefore, we demonstrate that actin filaments can function as biological "electrical wires" and can thus be conceptualized as nonlinear inhomogeneous transmission lines. This ability of actin filaments to conduct electrical signals may have important implications in the coupling of intracellular signals.

“…In the considered case, the soliton damping is the same as in a homogeneous viscous medium (see [77]). The motion of electrons and ions in a "cold" plasma with the magnetic field H 0 without allowance for collisions is described by the system of quasihydrodynamic and Maxwell equations [10]: H], ∂n α ∂t + div(n α v α ) = 0,…”

“…[4, 8, 14, 17, 20-26, 34, 47]). As applied to smoothly inhomogeneous regular media, the related problems are discussed in [77][78][79]. Analysis of the propagation of nonlinear signals in systems with random irregularities is of definite interest.…”
