摘要: 本工作应用脑内埋植慢性导管进行微量注射的方法,研究了背侧海马内注射乙酰胆碱及其M-受体阻断剂阿托品,GABA及其受体阻断剂印防己毒素,L-谷氨酸及其受体阻断剂4-羟基喹啉酸和受体激动剂海人酸、喹啉酸对大鼠巩固的操作式防御性条件反射的影响。结果表明:(1)乙酰胆碱、低浓度的印防己毒素、L-谷氨酸、海人酸、喹啉酸均对动物条件反射有暂时的促进作用。(2)阿托品、GABA和4-羟基喹啉酸均对动物条件反射有暂时的抑制作用。这些结果提示:海马内几种神经递质系统可能参与大鼠记忆再现的调制。

Abstract: We adopted the method of embeding the chronic canal in brain tomicroinject Acetylcholine and Atropine, GABA and Picrotoxin, L-Glutam-ate and receptor agonist kainic acid, Quinolinic acid, antagonist kynare-nic acid to dorsal hippocampus. The effects of such injection on the con-solidatory operant defence conditioning in rats were investigated. Theresults showed: (1 ) Acetylcholine, low concentration of picrotoxin, L-Glutamate,kainicacid and Quinolinic acid improved the complication of conditionedreflect activity. (2 ) Atropine, GABA and kynurenic acid impaired the above mentio-ned activity. These results suggested that some transmitter system in thehippocampus may be involved in memory retrieval modulation in rats.
