Physics shapes signals in nerves

In this short review, the importance of physics in understanding the signal propagation in nerve fibres is discussed. The main carrier of information is the action potential, but it is accompanied by mechanical and thermal effects. A possible model governing the ensemble of waves takes the basic laws of physics into account and describes the interactions between the dynamical effects. Such a model needs a corresponding mathematical formulation and, in this way, the interdisciplinarity combining electrophysiology, physics, and mathematics helps to understand the complex process of signal propagation in nerves measured experimentally.
