海马在延迟眨眼条件反射(DEC)中的作用仍然存在争议。在这里,我们调查了参与DEC的海马与柔和的音调作为条件刺激(CS)通过使用电解损伤或蝇蕈醇灭活豚鼠背海马。有趣的是,当一个柔和的音调被用作CS,海马的电解损伤显着延迟收购的条件反应(CR),蝇蕈醇注入海马明显抑制收购和表达的CR,但巩固良好的学习CR没有显着的影响。与此相反,电解质病变和蝇蕈醇失活海马产生的CR没有显着的赤字时,一个响亮的音调被用作CS。这些结果表明,海马是必不可少的DEC时,延迟任务变得更加困难。
The role of the hippocampus in delay eyeblink conditioning (DEC) remains controversial. Here, we investigated the involvement of the hippocampus in DEC with a soft tone as the conditioned stimulus (CS) by using electrolytic lesions or muscimol inactivation of guinea pig dorsal hippocampus. Interestingly, when a soft tone was used as a CS, electrolytic lesions of the hippocampus significantly retarded acquisition of the conditioned response (CR), and muscimol infusions into hippocampus distinctly inhibited the acquisition and expression of CR, but had no significant effect on consolidation of well-learned CR. In contrast, both electrolytic lesions and muscimol inactivation of hippocampus produced no significant deficits in the CR when a loud tone was used as the CS. These results demonstrate that the hippocampus is essential for the DEC when the delay task was rendered more difficult.
