Description
 

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:

  • Simulation of continuous conduction along non-myelinated axons
  • Simulation of salutatory conduction by means of a model experiment
  • Transmission of information by neurotransmitters
The set includes: Plexiglas trough, sand paper, 3 iron rods, 1 zinc electrode, 15 jackets for isolation of sections of the iron rod, detailed experimental instructions. The required chemicals (hydrogen peroxide, sulphuric acid, sodium chloride solution) are not included.
