Electrical stimulation of nerve fibers could promote the growth of the myelin sheath, a protective layer around neurons that is crucial for transmitting nerve impulses. The finding, published in the journal Biofabrication, introduces a new paradigm in the treatment of diseases where the myelin sheath is progressively lost, leading to muscular atrophy, hand and foot deformities, gait abnormalities, and paralysis.
