Abstract
The number and proportion of neurons according to their type and size in the Raphe Magnus Nucleus stained by the Golgi-Cox and Nissl methods were compared in male and female infants. Four female/male pairs aged from 2 to 150 days were studied. Wale females showed more neurons than males, males showed a higher proportion of large multipolar (more than 40 mum) and fusiform neurons (more than 20 mum) but not of ovoid neurons (more than 15 mum). These differences varied according to the type of cells and age of infants. Some of these results are similar to those found in the human Median Raphe Nucleus with the same methods.
