以前,我们已经证明Gluck和Myers(1993)的皮质海马模型可以扩展到Hasselmo和Schnell(1994)的假设,即隔海马胆碱能过程调节海马中的信息存储量。广义模型可以解释抗胆碱能药物东莨菪碱在延迟眨眼条件反射发作中的作用(Myers等人,1996年)。在这里,我们表明,该模型还占额外的眨眼结果,包括东莨菪碱被删除后快速恢复,保存潜伏抑制,学习无关和东莨菪碱下的灭绝,和海马损伤后没有影响的全身东莨菪碱。此外,该模型与有关内侧隔、外侧隔和海马局部注射东莨菪碱及其对眨眼条件反射的影响的数据一致。
Previously we have shown that Gluck and Myers’s (1993) corticohippocampal model could be extended to incorporate Hasselmo and Schnell’s (1994) hypothesis that septohippocampal cholinergic processes regulate the amount of information storage in hippocampus. The generalized model could account for the effect of the anticholinergic drug scopolamine in delaying onset of eyeblink conditioning (Myers et al., 1996). Here, we show that the model also accounts for additional eyeblink results, including quick recovery after scopolamine is removed, preserved latent inhibition, learned irrelevance and extinction under scopolamine, and no effect of systemic scopolamine after hippocampal lesion. Additionally, the model is consistent with data concerning localized scopolamine injections to the medial septum, the lateral septum, and the hippocampus and their effect on eyeblink conditioning.
