Saltatory Conduction Found in the Nervous System of Two Model Invertebrates, the Shrimp (Penaeus) and the Earthworm (Lumbricus terrestris)

As already described, the finding of the saltatory conduction phenomenon in the nervous system of a few invertebrate animals was mentioned in some neurobiological literature, but a conclusion on the lack of saltatory conduction in the nervous system of invertebrates had not yet been generally revised. The reason for this seemed to be that a saltatory conduction in invertebrates is based on the functional spots, which could not be accepted as a true node. Therefore, before presenting the experimental findings that demonstrate the phenomenon of saltatory conduction in the nervous system of invertebrates, it is necessary to discuss the common understanding of the true nodal structure of the myelinated fibers.
