Abstract
Four groups of male Wistar rats (4, 8, 18, and 24 months) were submitted to object recognition and spatial recognition tests. Object recognition was not significantly affected by aging even at a longer retention interval. On the contrary, spatial recognition was significantly impaired in 18- and 24-month groups. The existence of two dissociable neural systems, respectively involved in object and spatial recognition, is discussed.
摘要
将四组雄性Wistar大鼠（4、8、18和24个月）进行物体识别和空间识别测试。即使在较长的记忆间隔下，衰老对物体识别也没有显著影响。相反，18个月和24个月组的空间识别能力明显受损。本文讨论了分别参与物体和空间识别的两个可分离神经系统的存在。
