Quantitative study of the dorsal lateral geniculate nucleus of the rat during the postnatal development.
The chronology of dLGN development was studied in the rat from birth to 90 days postnatal (dpn). Our results indicate the faster dLGN growth occurs from 1 dpn to 21 dpn. The neuronal number and density was calculated. No significant neuronal loss was detected in the period investigated but the present study shows evidence of an important decrease (of 75%) in the neuronal density between 7 dpn and 21 dpn. Immediately the study of neuronal sizes and shapes was undertaken. Approximately at 14 dpn the deep neurons get a size significantly bigger than the marginal neurons. Finally, the different neuronal sizes were used for determining the successive phases of the neuronal development.
