ОписаниеModel for simulating the conduction of impulses along nerve fibres.
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 required chemicals (hydrogen peroxide, sulphuric acid, sodium chloride solution) are not included.
