Abstract
The present study was designed to investigate the possible deficits in the place learning on the 8-arm radial maze in aged rats. In this task, reward was given in the 4 predetermined arms. Aged rats (27 months old, N = 7) acquired this task more slowly than young rats (12 months old, N = 11), and didn''t reach to the performance level of the young rats within 80 training trials. Analysis of error choices revealed that the aged animals first entered in the unbaited arms more oftenly than the young rats, whereas there was no difference in the number of re-entered choices to the baited and unbaited arms between the aged and young animals. Therefore, it was concluded that learning deficits in aged rats were attributed to deficits in the reference memory but not in the working memory.This publication has 4 references indexed in Scilit:
