Great experiments for simulating the conduction of impulses along nerve fibers (according to Prof. Dr. Matthias Ducci / Prof. Dr. Marco Oetken). Exciting experiments for interdisciplinary teaching of fifth and sixth form classes. A model system for simulating the conduction of impulses is now finally available! Many biology teachers have complained about the lack of suitable model systems for simulating the conduction of impulses along nerve fibers, considering that neurophysiology is an established component of the sixth form syllabus. We have developed a unique electrochemical model experiment for effective illustration of this complex topic, in cooperation with Prof. Dr. Matthias Ducci (teacher training college PH Karlsruhe) and Prof. Dr. Marco Oetken (teacher training college PH Freiburg). Try it - you'll love it! The model experiments are based on the property of iron to develop a protective oxide coating in acid solutions under specific conditions. This impressive analogical model is based on the reversibility of the process of passivation and the appearance of a reactivation along a long iron rod. The materials provided allow the students to use the model to demonstrate continuous and saltatory conduction as well as the principle of transmission of neurotransmitters. The following experiments can be carried out:
