家兔在学习过程中海马电活动功率谱阵列的变化

CHANGES IN HIPPOCAMPUS POWER SPECTRUM ARRAY DURING LEARNING IN RABBITS

本文研究了家兔在学习时,其海马在条件反应形成中的作用。用计算机分析了海马脑电波功率谱阵列。结果表明:海马在学习初期起着重要作用;在学习后期虽然条件反应出现率下降了,但海马脑电功率却显著增强。说明了海马在建立整个条件反应过程中都处于积极活动状态。

It was the purpose of this paper to study the role of hippocampusin the formation of conditioned reaction during learning. The hippoca-mpus electro-activity spectrum power array was analyzed with the computer.The results indicate that the hippocampus plays an important role inthe early period of learning. In the later phase, although the appearancerate of conditioned reaction decreased, the hippocampus electro-activitypower increased gradually and significantly. This suggests that hte hippoca-mpus has been active during the whole process of conditioned reaction.
