Title: Mechanical Stimulation of Nerve Pulses.

Abstract: It has long been known that the application of a mechanical stimulus upon a nerve can trigger a nerve pulse. There is no single fundamental model from which all phenomena observed during the initiation and propagation of a nerve pulse can be deduced, however its electrical and chemical Êproperties have historically received more attention than its thermodynamic and mechanical properties. We present experimental results regarding mechanical stimulations of nerve pulses in lobster nerves and discuss them with respect to previous findings and in the context of the Soliton Model of nerve pulse propagation, which describes the nerve pulse as a soliton-like density (sound) wave which is dissipative and adiabatic. Results are also compared to electrical stimulations and recordings upon the same nerve samples.
