The myelin sheath's role is to rapidly move electrical
impulses along nerves, and if it is damaged — or demyelinated — then nerve function is compromised.
Researchers at the Niels Bohr Institute at the University of Copenhagen have now conducted experiments that raise doubts about this well - established model of electrical
impulses along the nerve pathway.

nerve impulses along the relevant
nerves to the brain, and, finally, the production of the sensation of sight.
