Quantitative analysis of myelinated axons of corpus callosum in the human brain.

In this study, the myelinated axons of the rostrum, genu, truncus and splenium parts of the corpus callosum were counted in the human brain by using a camera lucida. The numerical densities of these axons were compared with each other by means of quantitative analytical statistical methods. The number of myelinated axons of genu and truncus of the corpus callosum were found to be highest in number and they were nearly the same with each other. However, number of the myelinated axons of splenium was found to be lower in number, when compared with the other parts of corpus callosum.
