RESUMO
The spectra of fiber sizes at different depths of the optic tract of the opossum didelphis marsupialis were examined by electron microscopy in order to test for correlations between the eventual location of axons and relevant developmental events. Frequency histograms showed 1) a predominant representation of medium-sized axons and the virtual exclusion of coarse fibers from the deepest portion of that pathway, and 2) a progressive increase in the poportion of thin axons from deep to superficial sites of the tract. These findings are discussed in terms of the view of the optic tract as a chronological map of axon arrival
