在训练的前 4 天或 5 天中,训练前给予阿片拮抗剂纳洛酮可增强莫里斯水迷宫中空间信息的获取。纳洛酮治疗的大鼠比对照大鼠更快地学会了找到位于相对于环境线索的固定位置的隐形逃生平台。在第 5 天没有逃逸平台的情况下进行的探测试验中,纳洛酮治疗的大鼠也表现出对平台位置的更好了解。相反,训练后施用纳洛酮并没有显着影响表现,即使使用更高剂量或改变训练方案时也是如此。这些结果表明内源性阿片肽能系统在空间信息获取中的作用。
Pretraining administration of the opiate antagonist naloxone on the first 4 of 5 days of training enhanced the acquisition of spatial information in the Morris water maze. Naloxone-treated rats learned to find an invisible escape platform located in a fixed position relative to environmental cues more rapidly than did control rats. Naloxone-treated rats also displayed better knowledge of the platform location during a probe trial conducted in the absence of the escape platform on Day 5. In contrast, posttraining administration of naloxone did not significantly affect performance, even when a higher dose was used or when the training protocol was altered. These results suggest a role for endogenous opioid-peptidergic systems in the acquisition of spatial information.
