顶叶联合皮层（PC）受损的人类和猴子在视觉空间任务上表现出缺陷，这些任务通常取决于手头任务的注意力要求。为了测试人类和大鼠在空间信息处理的PC功能方面是否存在对应关系，在八臂径向迷宫上对两组大鼠进行了两项列表学习任务，一项是赢得停留任务，另一项是赢得转移任务。假设这两个任务在所需注意力努力的程度上有所不同，因为赢-转移规则比赢-停留规则更容易让大鼠学习。每种条件下的一组动物在接受双侧PC抽吸病变之前进行术前训练。每种条件下的另一组在训练前接受PC损伤。结果表明，PC损伤的动物不能获得赢-停留或赢-转移规则。然而，在接受术前训练的动物中，只有接受过Win-stay训练的动物受到脑损伤的不良影响。胜利转移动物的术后表现没有下降。由于PC病变的大鼠仅在更苛刻的空间任务中受损，因此这些结果与人类临床观察结果一致。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Humans and monkeys with damage to the parietal association cortex (PC) exhibit deficits on visual-spatial tasks that are often dependent upon the attentional requirements of the task at hand. In order to test whether there is a correspondence between humans and rats in terms of the function of PC in the processing of spatial information, separate groups of rats were trained in two list-learning tasks, a win–stay task and a win–shift task, on an eight-arm radial maze. It is assumed that these two tasks vary in degree of required attention effort, because the win–shift rule is considerably easier for the rat to learn than the win–stay rule. One group of animals in each condition was given preoperative training before receiving bilateral aspiration lesions of PC. Another group in each condition received PC lesions prior to training. The results indicated that animals with PC lesions are unable to acquire either the win–stay or the win–shift rule. However, of the animals with preoperative training, only the win–stay trained animals were deleteriously affected by the brain lesion. The win–shift animals showed no postoperative decline in performance. Because rats with PC lesions are only impaired on the more demanding spatial task, these results are consistent with the human clinical observations.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
