Abstract
Flechsig (1920) was the originator of the view that the degree of myelination of the CNS might be correlated with functional capacity. In his theory he stated that myelination started in projection pathways before association pathways, in peripheral nerves before central pathways, and in sensory areas before motor ones. Although he did modify his theory slightly because of his critics, he maintained that fibers always myelinated in the same order: first the afferent (sensory), then the efferent (motor), then the association fibers.
