利用小鸡建立学习和记忆模型的方法介绍

INTRODUCTION OF A METHOD IN ESTABLISHING A NEW LEARNING AND MEMORY MODEL WITH CHICKS

Gibbs和Ng利用一日龄小鸡作为学习和记忆的模型进行了一系列的实验研究,提出了记忆形成有短时记忆、中间记忆和长时记忆三个阶段的新假设。近年来,Patterson等人的工作不但证实了而且扩展了Gibbs和Ng的某些重要的发现。然而,Roberts则不同意Ng等关于记忆形成的三个阶段的论述。现在,双方正继续进行着有益的讨论。最近,我们对正常状态下一日龄小鸡的记忆形成进行了实验研究。结果表明,我们和Gibbs等人的结果大致上是相同的。 利用小鸡作为学习和记忆模型很有价值,并有许多优点。这个方法值得重视。

Gibbs and Ng conducted a series of experimental studies using one-tri-al taste-avoidance task in one day-old chicks and proposed a new hypo-thesis of three-stage model of memory formation, which is short-termmemory (STM), intermediate-term memory (ITM)and long-term memory(LTM). Since 1986 Patterson et al., have replicated and extended someof the key findings of Gibbs and Ng, But Roberts expressed doubts towardthis model. Now debate on both sides is still continuing. Recently, weundertook an experiment to study the stages of memory formation in nor-mal one-day-old chicks. Our results were similar to those of Gibbs andNg. Using chicks as a model for thestudy of learning and memory is ofgreat value and it has many advantages. This method is worthy of note.
