Neurofilaments serve as a necessity in brain sensory communications. They are important structural and cellular transportation proteins found in both afferent and efferent auditory neurons. The peripheral processes of auditory neurons innervate sensory hair cells within the cochlea and a loss of these hair cells, by disease or damage, is a major cause of deafness. The decline of Neurofilaments can also lead to the cause of multiple sclerosis due to their neurological involvement. This new book brings fascinating research in this field.
