Abstract: This presentation is dedicated to the study of myelinated nerve fibers. After an introduction to the historical background and to some mathematical modeling, a description of the propagative phenomena will be adressed. Thiswill include illustrations of experimental results obtained using a nonlinear electrical lattice. The study of ephaptic coupling between two adjacent fibers (with current loops) will then be developed, showing that axons are not only a meduim for propagation but also may take part in the computing process of neural information.
