摘要: 本实验目的是观察回避反应后间隔地电刺激海马背部,对建立空间辨别回避条件反射的影响。结果如下:在本实验条件下,刺激海马对建立条件反射初期有较大的干扰作用,其表现为训练第一天的条件反应率极低(5%),与各个对照组相比较,差异是显著的(p<0.001);训练第二天,条件反应率上升为51%,除与刺激皮层组有显著性差异外,与另外两个对照组之间的差异消失。可见,随条件联系的建立,刺激海马而引起的干扰作用减弱。因而,维持海马的正常机能是建立条件反射初期的重要条件。

Abstract: The purpose of this experiment is to observe the effect of electrostimulationof dorsal hippocampus after avoidance response on the establishment of spatialavoidance discrimination conditioned reflex. The results are as follows. The stimulation of hippocampus had greater interference in the estalishmentof conditioned reflex during the initial stage The reaction rate(5%) in theexperimental group was significantly lower (p<0.001)than that in the controlgroups. On the other hand, on the second day of training the reactive rateraised to 51%. There were no significant differences between the experimentalgroup and the control group Hence, the influence of stimulating hippoc-ampus on establishing conditioned re?lex was diminished, when the conditionedreflex became established. Our present data suggest that the maintenance ofnormal function of hippocampus in the initial stage of establishing conditionedreflex is important.
