ABSTRACT
UNLABELLED Possible discrepancies between an albino stock (Wistar), a mixed strain (pigmented/albino, Brown Norwegian x Lewis) and a pigmented strain (Long Evans) of rats in the acquisition and performance of a visual task for attention were investigated. It was expected that Wistar rats were less accurate in performance of the task, considering the visual deficits genetically linked to albinism in rodents. However, Wistar performed with the same accuracy, speed and impulsivity as Long Evans. The Brown Norwegian/Lewis rats had a decreased responding, speed and impulsivity. During task acquisition they responded with the same accuracy as the other two types of rats. After task acquisition they were also less accurate. IN CONCLUSION:
It seems reasonable to use Wistar rats as well as Long Evans for the present task.
