Abstract
In this paper we present an analysis of the visual sector of the Thala mic Reticular Nucleus (TRN) from 3, 6, 18, 24 and 30 month old Wistar rats using stereological methods. The volume density (Vv), the number of neurones per surface unit (Na) and the neurone numerical density (N v) showed a progressive decrease between the 3rd and the 24th months a s the animals aged, whereas a significant increase was observed betwee n the 24th and the 30th month, the period at which these rodents have fully entered old age.
