“SimNerv”-Simulation of Sum-Action Potentials in the Ischiadic Nerve of the Frog with a Virtual Physiology Lab

Abstract

Medical students have to study different aspects of sum-action potentials (SAP's) in the ischiadic nerve of the frog in their second year of German medical school. At some universities frogs are still killed for this purpose. Others use video clips to show the preparation and to reduce the number of experiments. There are also some computer-simulations in use which did not spread widely, yet, because of their user-unfriendlyness and partly unphysiologic responses. “SimNerv” is based on an algorythm which completely simulates SAP's. It is integrated in a virtual lab consisting of a stimulation chamber, a stimulator and an oszilloscope. Students learn about nerve conduction velocity, refractory time, anodic and cathodic stimulation, monophasic and biphasic action-potentials and the effects of local anesthetics. The program has been evaluated on 250 students with only 2% who disliked the didactical approach.
