Abstract
The influence of estrogen on the neurons and glial cells was examined in the phylogenetically younger, basolateral pan of neonatal rat amygdala (nucleus basolateralis and nucleus lateralis posterior). Neonatal rats were treated with a single dose of 1mg of estrogen on the postnatal day 3, and the [3H]—thymidine ([3H] TdR) incorporation was studied by means of autoradiography. On the postnatal day 10, in treated rats, the percentages of labeled neurons and glial cells significantly increased in nearly all of the nuclei investigated. The only exception was the unchanged percentage of labeled glial cells in the treated female rats (in both of investigated nuclei).
