What is it about?
The experimental study shows that nonlinear sound waves can be excited in a lipid interface that have similar shapes, amplitudes, velocities and most importantly a threshold for excitation as observed in single nerve fibers. It has been shown that the solitary pulse shape and the threshold result entirely from the elastic properties of the interface and do require any special proteins.
