Abstract

This article represents a response to Monakow's previous article. First, the author lists the law, according to which the fibers of the hemispheres are taxed with myelin; in general, these are the same laws as the author established for the rest of the nervous system. The first appearance of myelin fibers in the hemispheres refers to 21/2-3 months before birth; education of melin goes by precisely defined points; it is best to observe this process in infants who were born prematurely and lived for a while: premature functioning accelerates the formation of myelin mainly in projection systems, rather than in associative systems.
